The 'Reality' of Dreaming: Why isn't Every Dream Lucid?

Dreams are the ultimate form of fantasy - we are so immersed in the landscape and narrative of our dreams that we accept them as our reality while we are in the dream world. Unless we are lucid dreaming, we only identify the dream as distinct from our ordinary perception of conscious reality when we awaken and start to compare the dream to what we know to be true of waking life.

In my time spent on online lucid dreaming forums, I stumble across many anecdotal claims from oneironauts who claim they can experience several lucid dreams per night, every night; or alternatively, complain that they lucid dream 'too much'. I find it very hard to believe that these people experience lucidity so frequently, especially given that many of them claim that they learned to lucid dream through lucid dreaming induction methods (so, were not natural lucid dreamers) and their lucidity continues even when they are not actively trying to induce a lucid dream. 

I am not suggesting that it is wholly impossible for someone to experience a lucid dream every night - Perma-Lucid Dreamers account for a very small fraction of those who can lucid dream. It's just not the norm for someone to suddenly start lucid dreaming on a nightly basis just because they averted their mind to the desire to learn how to become lucid. Often Perma-Lucid Dreamers are not aware their dreams are lucid, or different from those experienced by the general population - because they do not have a comparison by which to recognise this.

This led me to research why we don't lucid dream every time we fall asleep. For new readers, a lucid dream is one in which you are consciously aware that you are dreaming while in the dream state - it may be possible to change or control what happens in the dream, but this is not necessarily true of all lucid dreams. I have many lucid dreams where I cannot control anything, and all my attempts are frustrated or impossible.

In order to address why we don't lucid dream every night, I decided to read up on Depth Theory - the study of the unconscious, interpersonal aspects of human experience, which focuses on the phenomenon of dreaming as well as complexes and archetypes. Many Depth Theorists follow Jungian psychology, which addresses the concepts of the psyche, human development, personality formation, and individuation. Individuation is a process of bringing our unconscious potential into a concrete living reality - it is a process which helps to secure a bridge between an individual and the unconscious, as well as the individual and his/her wider social community. By incorporating both an inner and outer exploration, a person can discover a more potent sense of meaning and purpose in life. Carl Jung (1875 - 1961) believed that psychological distress is a result of an imbalance within the individual that often is experienced as an alienation from the deeper personality - known as the 'Self'. Jungian psychotherapy seeks to restore the individual’s connection to the Self. This effort can be achieved through the therapeutic relationship, dream interpretation, active imagination, and work with expressive therapies.

This theory suggests that in order for our dreams to provide us with a form of unconscious therapy while we sleep, we must be passive within the dream state. The dream can only help us to achieve catharsis, healing or personality integration if we accept the reality of the dream as genuine. The brain is almost hardwired to avoid lucidity in the dream state - parts of the brain that we use during our waking lives, such as the logical, fact-checking part of the brain - are deactivated during sleep, to allow us to dream freely and unconsciously. One theory is that we need to accept the dream as reality so as not to arouse ourselves into wakefulness. 

The brain is responsible for interpreting sensory perceptions - sight, sound, smell, taste and touch. However, it is also able to process other information - such as imagination, dreams, hallucinations etc. When asleep and dreaming, the brain does not tend to discriminate between the types of input it receives and therefore, the brain does not alert the dreamer to the fact they are dreaming, rather than experiencing waking reality because the conscious part of the brain is switched off. The brain operates in such a manner that it actually creates false memories to explain the dream content and fool us further into accepting it as reality. One way of becoming lucid is to train yourself (using cognitive methods) to identify dreamsigns - the bizarre or impossible events of a dream which could only occur if you were dreaming - and confirm you are in a dream state by performing a reality check. But even for seasoned lucid dreamers, this isn't always as straightforward as it sounds - essentially, when we teach ourselves to induce a Dream-Initiated Lucid Dream (DILD), we are hacking our brains and overriding what our brains are biologically programmed to do.

There is another explanation for why not all our dreams are lucid - from the perspective of Developmental Psychology. This holds that when we were foetuses in the womb, we experienced dreams - before we were even aware of the laws of physical reality and logic. These foundational, inuetro dreams may leave impressions on our subconscious, which is a reason why we do not necessarily challenge the reality of the dream and become lucid in all the dreams we experience in later life, even after we attain knowledge as to how our waking life affects our subconscious dream world. 

Developmental psychologist Jean Piaget (1896 - 1980) studied children’s dreams and described how children’s acceptance of dreams gradually change from a firm belief of dreams as reality to an awareness that dreams are just a 'story' inside their minds while asleep. This explains why we may begin our sleeping life believing that dreams are real because we are born dreaming. Newborn babies are in the REM sleep state for an average 8 hours per day. REM is the sleep period considered most favorable and fertile for ordinary (non-lucid) dreaming. The dream world is, in many ways, our first and natural world, and the waking world with all of its rules comes later.

Why Do We Accept the Bizarre Reality of Dreams?

This leads me to an interlinked subject - why do we accept our dreams as real while we are dreaming them?

When addressing the altered reality of our dreams, we might look to the research of Sigmund Freud (1856 - 1939) who also believed that dreams were a form of therapy or emotional healing process. In order for us to resolve an inner conflict or obtain wish fulfilment, we must believe in the reality of the dream, and therefore, in the dream state critical thinking and doubt are repressed so that we can fully believe in the dream. 

Psychologist Allan Hobson adopts a neurological approach to dreaming, which challenges the idea that dreams have any intrinsic meaning to us. He claims that dreams are simply makeshift and inconsequential narratives, stemming from random brain activity while we sleep. The dreamer makes the best of a bad script, and the result can be nonsensical or bizarre. Due to the fact that areas of the brain that sustain working memory are weakened while we sleep, logic is compromised during dreams. Hence, the dreamer accepts these bizarre situations and transitions in time and space as real.

Theories of Dreaming

Here are some key theories as to why we dream and why we might accept the reality of the dreamstate: 

1. We Dream to Practice Responses to Threatening Situations

This is the 'Threat Simulation Theory' propounded by Antti Revonsuo, a Finnish cognitive scientist, who produced evidence to show that our amygdala (the area of the brain responsible for the 'fight-or-flight' response) fires more than normal during REM sleep  In REM sleep, the brain functions in a similar way to when it's specifically threatened for survival during waking life. In addition, the part of the brain which practices motor activity (running, fighting) fires increasingly during REM sleep, even though the limbs are still due to muscle atonia/sleep paralysis. Therefore, Revonsuo and other evolutionary theorists argue that in dreams, we are actually rehearsing fight-and-flight responses, even though our limbs are not actually physically moving during sleep. Revonsuo believes that dreams are an evolutionary adaptation - we dream in order to rehearse behaviours of self-defense in the safety of night-time isolation which prepares us for actual waking situations where me may need to utilise these skills for survival. This explains why mammals (specifically cats) - who also experience REM sleep and dreams - have been shown to 'act out' hunting dreams when the part of the brain responsible for REM muscle atonia/sleep paralysis has been deactivated or removed. Hunting is a means of survival for a cat in the wild - and seeing the acting out of physical movements associated with hunting and catching prey allows us to identify the possible content of the cat's dream. As modern humans, our dreams tend to reflect waking life concerns and emotions - we might see these are modern versions of 'threats' to our survival given that the majority of people living in the developed world no longer need to rely on hunting and gathering as a means of survival, nor need to physically protect ourselves from predators.

2. Dreams Create Wisdom

If we remembered every image of our waking lives, it would clog our memories. So, dreams sort through memories, to determine which ones to retain and which to lose. Matt Wilson of the MIT Center for Learning and Memory argues this perspective. In one study, Wilson put rats in mazes during the day, and recorded the patterns of neural activity as the rats negotiated the maze. When he watched the rats enter REM sleep, he saw that the same neuron patterns fired as those which had fired at choice turning points in the maze. In other words, he saw that the rats were dreaming of important junctures in their day. Wilson argues that sleep is the process through which we separate the memories worth encoding in long-term memory from those worth losing. Sleep turns a flood of daily information into what we call 'wisdom' - and we can use this acquired intelligence in real waking decision-making.

3. Dreaming is Like Defragmenting your Brain's Hard Drive

Francis Crick (who co-discovered the structure of DNA) and Graeme Mitchison put forth a famously controversial theory about dreams in 1983 when they wrote that 'we dream in order to forget'. This means that the brain is like a machine which connects its data in certain ways (obsessing, defending or retaining), and that those thinking pathways might not be the most beneficial for us. When we sleep, the brain fires much more randomly and this random scouring for new connections allows us to loosen certain pathways and create new, more advantageous ones. Dreaming is a shuffling of old connections that allows us to keep the important connections and erase the inefficient links - analogous to the defragmentation of a computer's hard drive. Dreams are a reordering of connections to streamline the system.

4. Dreams are a Form of Psychotherapy

For many theorists (including Freud) dream are principally a means by which to confront difficult and surprising emotions and deal with those emotions in a new way. Ernest Hartmann, a doctor at Tufts, focuses on the emotional learning which happens in dreams, developing the theory that dreaming puts our difficult emotions into a visual language. In dreams, we deal with emotional content in a safe place, making connections that we would not make if left to our more critical or defensive waking brains. In this sense, dreaming is like a form of psychotherapy - we think through emotional stuff in a less rational and defensive frame of mind and are able to come up with solutions which may not be available to the conscious mind. Through that process, we also come to accept truths we might otherwise repress. 

5. The Absence of Theory

Others - such as Hobson, above - argue that dreams have no meaning at all - they are merely the random firings of an unconscious brain. The mind is still 'functioning' insofar as it's producing images, but there's no conscious sense behind the narrative. Perhaps it's only consciousness itself that wants to see some deep meaning in our brains at all times and therefore our waking brain projects meaning onto the meaningless dream content in order to explain our experience of dreaming.

Normal Non-Lucid Dreams v Lucid Dreams 

- A Neuroscientific Comparison

In order to understand the difference between normal dreams and lucid dreams, we can identify neurological differences between these distinct brain states. This sheds some light on why we might accept normal, non-lucid dreams as reality and do not question events in the same way we would if awake or in a lucid dream. A very interesting journal article tackled this precise theme - see Dresler et al, 'Neural Correlates of Dream Lucidity Obtained from Contrasting Lucid versus Non-Lucid REM Sleep: A Combined EEG/fMRI Case Study' (2012) Sleep 35(7), 1017 - 1020. I have summarised the findings of the study, below for the purposes of discussion:

In REM sleep we experience the most vivid and intense forms of dreaming - however, these dreams (when non-lucid) are deficient in reflective thought and metacognition. Instead the internally generated perceptions and emotions experienced during dreaming typically show many cognitive peculiarities, with a bizarre dream narrative full of gaps, delusional thought, and a complete lack of insight into the fact that we are dreaming. These cognitive constraints (i.e. lack of awareness or rationality) are thought to be related to the neural activation patterns associated with REM sleep, particularly deactivation of the dorsolateral prefrontal cortex.

In contrast to normal dreaming, lucid dreaming denotes a rare state of sleep comprising cognitive features of both waking and dreaming. During lucid dreams, subjects become aware of their dreaming state, have full access to memory, and are sometimes able to volitionally control dreamed actions. Although standard polysomnographic criteria of REM sleep are maintained (and REM sleep muscle atonia - commonly referred to as sleep paralysis - prevents overt motor behaviour), lucid dreamers are able to communicate their state by predefined volitional eye movements, clearly discernable in the electrooculogram. 

Lucid dreaming can be trained and has been successfully utilized for the treatment of nightmares or post-traumatic stress disorder (PTSD). However, neural changes which accompany dream lucidity, and their role in the amelioration of dream disorders, are not yet well understood. When compared to non-lucid REM sleep, lucid dreaming is associated with increased 40-Hz activity (known as 'gamma brainwaves'), and increased coherence in frontal regions, as has recently been shown by quantitative EEG. Neuroimaging data, delineating the neural correlates of lucid dreaming, have not yet been obtained and analysed. While in a later study Dresler and his colleagues analysed how the skill of lucid dreaming served as a tool for tracing specific motor activity in dreams, the current study aimed to reveal the neural correlates of lucidity per se by contrasting lucid vs non-lucid REM sleep using a combined EEG/fMRI approach.

Neuroimaging studies have shown that human REM sleep is related to characteristic patterns of regional brain activity - during REM sleep, neural activity in the brain stem, thalamus, amygdala, and extrastriate temporo-occipital cortices increases, while the dorsolateral prefrontal cortex and the precuneus show deactivation. 

This specific pattern of neural activity has been proposed to reflect the visual hallucinations, emotional intensifications, and cognitive abnormalities typically experienced in dreams. In contrast, lucid dreaming is characterized by a regaining of higher cognitive capabilities, eventually leading to the awareness of the dreaming state. 

Recent quantitative EEG data have shown that this 'waking' intellectual clarity is paralleled by neural activations in frontal and frontolateral regions. Likewise, PET data show cognitive control in dreams to be associated with activation of frontal cortex components.

In the current study, Dresler and his colleagues present neuroimaging data showing lucid dreaming to be associated with neural activations in a specific network of cortical regions. In line with the study of Voss et al (see 'Lucid dreaming: a state of consciousness with features of both waking and non-lucid dreaming' (2008) Sleep, 32, 1191 - 200), during lucid dreaming the researchers observed increased activity in the right dorsolateral prefrontal cortex. The dorsolateral prefrontal cortex is thought to underlie a wide range of higher cognitive capacities, as evidenced also by the dysexecutive syndrome seen in patients with lesions in this region. In particular, the right dorsolateral prefrontal cortex was associated with self-focused metacognitive evaluation. 

While in normal dreams, working memory is strongly impaired, activation in the dorsolateral prefrontal cortex (in combination with parietal lobules, which were also found to be activated during lucid dreaming) may reflect working memory demands related to task performance in the study. Further, there was observed increased activation in bilateral frontopolar areas, which have been related to the processing of internal states - i.e. the evaluation of one's own thoughts and feelings.

The strongest increase in activation during lucid compared to non-lucid REM sleep was observed in the precuneus - a brain region which has been implicated in self-referential processing, such as first-person perspective and experience of agency/autonomy. While in normal dreams, attention is often hyper-associatively driven by the (pseudo-)external dream scenery, lucid dreaming is - by definition - characterized by a reflection on one's own state of mind.

Interestingly, Dresler et al found activation in the bilateral cuneus and occipitotemporal cortices. These areas are part of the ventral stream of visual processing, which is involved in several aspects of conscious awareness in visual perception. While these activations seem initially puzzling, since non-lucid dreams are also characterized by vivid dream imagery - they are in line with anecdotal reports of lucid dreamers who state that lucidity is associated with an exceptional brightness and visual clarity of the dream scenery.

While lucid dreaming is an intriguing phenomenon in its own regard, it can also serve as a tool for the study of dream disorders - for example, nightmares and PTSD. Neurocognitive models of disturbed dreaming emphasize a hyper-responsivity of the amygdala in nightmare generation, coupled with a failure of medial prefrontal regions to dampen this activation. Lateral prefrontal regions have been shown capable to influence amygdala function through connections to the medial prefrontal cortex. Increased lateral prefrontal activation during lucid dreaming therefore fits well with the therapeutic effects of lucidity training on recurrent nightmares. 

If lucid dreaming can also be utilized in the treatment of other dream disorders - for example, terrifying hypnagogic hallucinations, or pathological dream vivification, is an open question that warrants further investigation and research studies. In summary, the study by Dressler et al found that, in line with recent EEG data, lucid dreaming is associated with a reactivation of several areas normally deactivated during REM sleep. This pattern of activity can explain the recovery of reflective cognitive capabilities that are the hallmark of waking life and also lucid dreaming.

Lucid Dreaming - Why Lucid Dream?

You can transform your life in the dream state through the practice of lucid dreaming. It can be used for spiritual practice and growth, enhancing psychological integration; because lucid dreaming is all about being consciously aware of what is essentially a subconscious experience (dreaming), the mind is turned inwards, so the dreamer is able to examine their own psyche at work. Cultivation of lucid dreaming forms a cornerstone of Tibetan Buddhist Dream Yoga practices, a topic on which I hope to write an introductory article in the near future. Although I do not approach my own lucid dreaming explorations from Buddhist principles, it is incredibly useful to gain an insight into the reasons other cultures and traditions use the lucid dream process for spiritual enrichment.

Lucid dreaming has been described by Charlie Morley (author and lucid dreaming expert and teacher) as showing us the flexibility of our life experiences and the notion that we are projecting an aspect of our reality, allowing us to manifest certain desirable qualities or actions. Morely also states that lucid dreaming is a very literal form of 'co-creating' because in the lucid dream, the dreamer is both the dreamer and the dreamt of; the projector and the projected. You can directly observe how the lucid mind projects and manifests images and experiences and take this learning into your waking conscious, as a process of integration between body and mind. Morley, like myself, is sceptical as to whether we can simultaneously 'share' the lucid dream experience with another person, arguing that the phenomenon should be tested in dream experiments (he, like myself, has had limited success) - and explaining what some describe as shared dreams as little more than daily residue from a shared waking experience (such as a trip to the zoo) influencing dream content in dreamers (for example, both dreamers reporting dreams about a tiger the night after a visit to the zoo).

There is some evidence that lucid dreaming has been used as a form of 'training ground' for athletes or creative individuals who harness the process as a way of learning and practising skills and methods they wish to embody in their waking lives. Research has shown that some of the procedural memory for fine muscle movements (or 'muscle memory' as it is otherwise known) for playing musical instruments can be increased during a lucid dream. LaBerge and Rheingold cite a surgeon who would polish and refine his surgical skills (based on pre-sleep examination of his real-life surgical case-load) which enabled him to perform surgical procedures quicker and more effectively than the average surgeon, crediting his lucid dream surgical training as an explanation. Research by Dr Erlacher at the University of Bern in 2010, found that practising a physical activity in a lucid dream improved waking performance. He asked subjects to perform 20 attempts at flicking a coin into a cup, before they went to sleep. Those who practised the activity during a lucid dream that night, were found to be more accurate in the same tests the next morning, compared the those who did not practice in a lucid dream, or the control group, who did not lucid dream at all. Dreams are also a furtive breeding ground for the creative arts - painters such as Salvador Dali, William Blake and Paul Klee, used their dreams as source material for their art. Lucid dreaming and dreaming in general may enhance the dreamer's conceptual or symbolic understanding and offer them new ways of visually presenting thoughts or emotions which may not have come to them in their waking consciousness. Likewise, in music, Beethoven, Wagner and Mozart all found inspiration within their dreams. Dreams reveal our creative capabilities in ways the waking brain may not be able to - because during the dream process our ideas can flow free without being filtered by reason or rationalisation. 

Lucid dreaming has often been used as a way of confronting and resolving fears and phobias. Within the lucid dream state, time and space is relative - Morley likens the experience to jumping out of a plane - while the free fall may only last a minute or so, the experience may feel or be perceived as lasting a lot longer for the jumper. This is also true of the lucid dreaming experience, which means that even in a brief lucid dream (which in 'real time' only lasts a matter of minutes), a significant amount of  psychological insight or healing can take place. Much like the theory that nightmares are a way of presenting the dreamer with anxiety-provoking mental symbolism in a narrative form, as a therapeutic aid to dealing with such material and preventing it from negatively affecting our waking mind, lucid dreams enable us to manipulate our experiences and intentionally bring us into contact with the sources of our fears and phobias, giving us a safe opportunity to tackle and overcome them, with endless possibilities which may not be appropriate in waking like 'Exposure Therapy' or psychological 'Flooding' techniques. For example, if the individual's phobia is not one to which they can be exposed in a clinical environment (for example, they fear ghosts or demons) or the method of confrontation would not be ethically appropriate or even possible (i.e. slaying a giant spider to overcome extreme arachnophobia), lucid dreams may enable the individual to take advantage of the rationales behind such therapeutic methods in the comfort of their own bedroom and produce similarly positive effects. The lucid dreamer can use the lucid dream experience to visualise and project that which they wish to interact with - or conquer - and will still feel the same emotions which would accompany a waking experience of interacting with the person or object, but will know that what they are seeing and feeling is nothing but a mentally-created illusion, no matter how realistic or true to waking reality it appears to be. Nevertheless, the brain will create neural pathways based on this experience, which can be reactivated in the waking state and so the lucid dream states allows the dreamer to work with traumas and fears which benefits them in waking consciousness. 

In a study conducted at the University of Milan (Universita degli Studi di Milano), Italy in 2009, it was posited that lucid dream training may be a useful tool in dealing with chronic, recurrent nightmares and traumas, instead of the current trend for prescribing suppressant medications. This embraces the 'Threat Simulation Theory', which I will cover in more detail in a subsequent article, but in short, works on the assumption that dreams and nightmares serve an evolutionary function of exposing us to, and allowing us to rehearse, our reactions to dangerous situations. By rehearsing our 'fight or flight' processes in the dream state we are better prepared to deal with the same or similar situations if they arise in our waking life. Lucid dream training to deal with recurrent nightmares or traumas works on the same evolutionary and biological principles, but allows the dreamer to intentionally manipulate their dream content and experience in order to fast-track or improve their responses as well as the underlying healing processes involved. In a nightmare, the first instinct of the dreamer is to wake up because they are not ready or willing to confront their fear - this is natural and perfectly fine. but at some point they may be able to stay in the nightmare, and if in a lucid state, will be consciously aware that this is simply a projection of their mind Often all it takes to overcome the nightmare in a lucid dream state, is to bear witness to what it is which frightens the dreamer - to acknowledge it and recognise is as a visualisation of a subconscious emotion or thought. If the dreamer is able too become lucid during an incidence of a recurrent nightmare, it has been found that just one exposure is enough to end the nightmare cycle from reoccurring, 

Every time you experience a lucid dream, you become more apt at distinguishing between reality and unreality - i,e, waking expectations and the environment of the dream state, and thus, neuroscientific and psychological research has found that frequent lucid dreamers perform better at cognitive problem solving because the brain is adapting and learning new skills and abilities. Lucid dreaming reveals the incredible power of the human brain.

Aside from the psychological benefits of lucid dreaming, one of its mist compelling attractions for most oneironauts, if the fact of the limitless possibilities and freedoms for escapism.The lucid dream is the ideal scenario for fulfilling deep wishes and desires, many of which might be inaccessible or completely impossible to achieve in waking life, Many lucid dream enthusiasts use their dreams for experiencing erotic liaisons, animating a particular fantasy, meeting an idol or pursuing physically inconceivable feats, such as flying or becoming invisible. Otherworldly or fantastical scenarios and situations are now painted in stunningly vivid realism, and the dreamer is able to manipulate and control their interactions with the self-created and tangible dream environment, almost as if they were starring in their own subconscious movie. The scope of the lucid dream experience spans the length and breadth of the dreamer's imagination, but is projected in sensational detail, highlighting the dreamer's ability to mentally depict a believable, 3-dimensional location and functioning narrative, with an uncanny capacity to mimic the most minute elements of reality.The lucid dream world is perfect for exploring the depths of the subconscious mind in a safe and healthy way. 

Lucid dreams also prompt us to analyse the nature of reality. There are some philosophies which question whether it is consciousness which creates reality and lucid dreaming provides us with a direct line of communication with our subconscious mind. Using the lucid dreaming experience, we are able to conduct our own philosophical enquiries into the nature of reality and unreality, for example, why in the dream state there is a fundamental break down of the laws of cause and effect and also our concepts of time, space and the dimensions of our physical reality. We can use the lucid dream experience as a lens for our unconscious and allow us ourselves to discover what our dreams reveal about our interactions with physical reality, time and space. It therefore provides a great comparative experience to reflect upon the waking reality. It is an alternative to psychedelic drugs (which may be illegal and/or highly dangerous), and the furthest we can safely travel outside our usual waking perceptions and sense of reality, while still retaining the clarity of thought which is unlikely to exist during a drug trip. There are none of the adverse consequences of ingesting psychedelic or dissociative drugs. Lucid dream creates a natural high - including feelings of intense excitement, euphoria and adrenaline rush, in addition to stimulation of the senses and altered perception. 

There is some research that suggests lucid dreaming can help you grieve for departed loved ones, by giving the dreamer the opportunity for posthumous meetings and interactions with the deceased. Thus, lucid dreaming might be therapeutic during the mourning processes, allowing them to replay cherished memories or reach closure on unfinished business. 

This article has discussed a few of the main reasons why people may choose to lucid dream, but of course the explanation for why this is such an increasingly popular phenomenon, are as plentiful as the possibilities within the lucid dream experience itself. Lucid dreaming allows you to expand your horizons and connect with the subconscious mind and psyche in a magical reality of your own creation.
