Dreaming as Play and as Mind-Wandering

The neuroscience of dreams has shifted in recent years toward the idea that dreaming can be conceived as a kind of mind-wandering in sleep. According to current evidence, mind-wandering (also known as day-dreaming, or drifting thought) is a product of the “default mode network,” a system of neural regions that remains active in the absence of external stimulus or focused thought. During sleep this same system of neural regions becomes active, helping to generate the experience of dreaming.

Two recent books by esteemed researchers make this argument about the connection between dreams and mind-wandering: When Brains Dream: Exploring the Science and Mystery of Sleep, by Antonio Zadra & Robert Stickgold, and The Emergence of Dreaming: Mind-Wandering, Embodied Simulation, and the Default Network, by G. William Domhoff. When scientists of the stature of Domhoff, Stickgold, and Zadra reach a common conclusion, it’s worth taking the idea very seriously.

Mind-Wandering and Play

However, the valuable implications of this idea remain obscure when expressed in research terminology. I suggest a more helpful framework is provided by the concept of play. Mind-wandering is, in this view, the mind at play. And dreaming is the play of the mind while asleep. Released from external demands and left to its own devices, whether awake or asleep, the mind becomes active in a more spontaneous, imaginative, emotionally variable, and freely associative mode. If this is not identical to mind-wandering, it at least shares so many core features with play that we should consider the benefits that come from further studying this connection.

The Play of Animals

There is a rich scientific literature on play behaviors in many animal species, all of which can provide dream researchers with valuable evidence, surprising insights, and a stronger grounding in the evolution of our own species. According to comparative zoologists, play in animals is centrally involved in learning and practicing survival-related skills, especially at the younger stages of life and especially for species who live in complex social groups. These features of play correlate very closely with prominent features of dreaming, not excluding the widespread occurrence of terrifying dreams of fear and vulnerability, which seem at first sight to be entirely unplayful. However, the most common form of play in the animal kingdom is play-fighting, which helps to account for the prevalence, and even value, of nightmares in healthy human development. Our fundamentally playful dreams include a great deal of the fighting kinds of play. Although distressing in the short-term, such dreams have the beneficial long-term effect of priming our waking awareness to be vigilant toward similar threats in the waking world.

The Science of Creativity

How does the mind generate novel ideas in art, science, technology, and daily life? Research on mind-wandering is clearly relevant to this important question, insofar as the creative process seems to depend on a moment of unforced openness to serendipity, to a flow of spontaneous images, feelings, and ideas emerging from the unconscious mind. These moments of openness to the unconscious regularly occur in dreaming while asleep, which is why dreams have always been considered a source of creative inspiration.  These moments also occur in playful activities while we are awake, alone or with others, when our focused attention is temporarily suspended and the curious explorations of the wandering mind can yield unexpected insights and discoveries.

Psychotherapeutic Dialogue

The connection between play, dreaming, and mind-wandering has practical relevance for clinicians and caregivers who work in play therapy, art therapy, or any therapeutic approach in which an open dialogue is part of the healing process. Sigmund Freud was one of the first to recognize the therapeutic value of “free association” as a technique of encouraging clients to say whatever spontaneously comes into their minds, as a way of eluding the critical judgment of consciousness and honestly expressing their unconscious feelings. Psychotherapy in this sense has the quality of shared mind-wandering. It creates a safe, playful space in which the clients can, with their therapist as a companion, freely explore questions and conflicts relating to important concerns in their life.

Philosophy

This might sound like more of a stretch, but research on mind-wandering, if slightly reconceived, can also help shift the philosophy of dreaming toward a deeper appreciation for what we experience during dreams. The concept of play is central to Friedrich Schiller’s On the Aesthetic Education of Man (1795), a key text for the early German Romantics which suggested that play enables us to achieve a higher union of the mutually opposing needs of our mind and body, intellect and desire, reason and sensation. “Man plays only when he is a man in the full sense of the word,” Schiller stated, “and he is only a complete man when he plays.” If dreaming is indeed a legitimate form of play, we can draw on the reflections of Schiller and his colleagues to affirm the philosophical significance of both dreaming at night and mind-wandering during the day as paths toward a more fully integrated and actualized sense of self.

The Distinguishing Features of Big Dreams

If someone presented you with two sets of dreams, one of most recent dreams and one of highly memorable dreams, you could predict with a high degree of confidence which type of dream was in which set, based only on word usage frequencies.

The set with more references to flying, air, family, animals, fantastic beings, Christianity, and death is more likely to consist of highly memorable dreams.

This is a testable hypothesis that emerges out of a comparison of the SDDb baselines for most recent dreams (MRDs) and highly memorable dreams (MemDs), available here.  To be clear, it’s a prediction of probability, not certainty.  Some highly memorable dreams have none of these elements, while some most recent dreams have several of them.  But according to the SDDb baselines, it is the statistical tendency of highly memorable dreams to contain significantly more of these elements than we generally find in most recent dreams.

Whether or not this hypothesis has any practical application, it adds new evidence in support of the theoretical claim that dreams are meaningfully structured not just for the individual dreamer but also in relation to each other.  There really are different types of dreams, and their differences can be expressed in increasingly precise terms.

Other researchers such as Harry Hunt and Don Kuiken have proposed psychological models to account for different types of dreams (what Hunt calls “the multiplicity of dreams”).  I am not yet at the point with the SDDb baselines to feel comfortable engaging directly with their approaches, but that is definitely a long-term goal.

At this stage I want to look more closely at the higher-frequency MemD elements and try to understand what they might contribute to the dreams’ long-term impact on waking awareness.

Flying: Not all dream references to flying involve magical powers–some relate to the flight of birds, or flying on airplanes, or floating in water, or time “flying” by.  But many of the references are indeed about people flying magically, and I think it makes good sense that overall, MemDs have significantly more flying references than MRDs.  I would be surprised if it were otherwise, based on the recurrence of magical flying dreams through cross-cultural history.  Genuine flying dreams tend to be quite vivid and realistic, and it’s reasonable to assume that such unusually stimulating sensations would make a lasting impact on waking awareness.

Air: Some of the air references occur in flying dreams, but in most MemDs the air references appear in different contexts: the dreamer is struggling to breathe, or facing a tornado, or noticing the wind blowing.  I don’t know about dreams of wind, but certainly with dreams of tornados and potential suffocation the memorability of the experience is likely to be very high.  A tornado is the most powerfully destructive form of air in nature, and suffocation is a perennial threat to human life, perhaps especially in sleep for people who snore or have apnea.

Family: References to family members appear often in MRDs; they appear even more often in MemDs.   I think it’s fair to say that most people’s strongest emotional relationships (both positive and negative) are with family members.  Thus it makes sense that their appearance in a dream correlates with high memorability.  Looking in more detail at the word search results, references to parents (e.g., mother, father, mom, dad) tend to be the highest, suggesting that dreams in which the individual is cast as a child or in a child’s role are more likely to be memorable.

Animals: Based on any of several different theories (psychoanalytic, developmental, evolutionary), it could be expected that MemDs would have a higher proportion of animals than MRDs.  Psychoanalytically, animals symbolize powerful instinctual energies. Developmentally, animals appear more often in children’s than in adults’ dreams, and MemDs are often recalled from early in childhood. In evolutionary terms, animals in dreams may reflect ancestral threats that we are innately primed to notice and remember.

Fantastic Beings: This category by definition includes characters who are not “real,” so their appearance in dreams naturally arouses some degree of heightened awareness and emotional impact.  Many of them are perceived as extremely frightening and dangerous to the life of the dreamer.  I was surprised by the SDDb baseline results that the MemDs do not have more fear-related emotions than the MRDs, but perhaps what makes some MemDs different is the supernatural source of the fear. There is a connection to be made here with the notion of “minimally counterintuitive supernatural agents” as used in the cognitive science of religion–dreaming is a rich experiential source of people’s religious and spiritual beliefs about such beings.

Christianity: Many references to Christianity in both MRDs and MemDs are relatively trivial references to Christmas, or mild oaths, or a person’s name.  But more often in the MemDs there are direct references to interactions with Jesus, battles with demons, visiting heaven, and worshipping in church.  In a majority-Christian country like the U.S., where all the SDDb baseline participants reside, this seems like an expectable result.  Insofar as Christianity, like most religions, is concerned with deep questions of morality, suffering, and faith, any dream that refers to religious teachings is likely to register more memorably in the dreamer’s awareness.

Death: Whether considered in religious or secular terms, death surely counts as a major existential concern of human life.  Dreaming itself has long been mythologically associated with death, and cultural traditions all over the world have stories about dreams as a portal to the afterlife.  In MemDs the theme of death takes many forms: other characters dying or being killed right in front of the dreamer, dead relatives appearing as if alive (i.e., visitation dreams), and, more rarely, the dreamer him or herself dying.  When the prospect of mortality arises in a dream, it’s not surprising that the individual takes notice and remembers.

What do these seven higher-frequency MemD elements have in common?

For one thing, several of them involve “counter-factuals,” i.e., phenomena that are literally impossible in ordinary waking life.  Magically flying in the air, encountering fantastic beings, seeing people who are dead appear as if alive–these are strikingly anomalous experiences that stand out from ordinary life and make a big impression on memory.

Secondly, several of the MemD themes involve dire threats to the individual’s life and well-being.  Dreams of death, demons, monsters, wild animals, suffocation, and tornados naturally arouse a host of psychological and physiological responses that can literally seize the dreamer’s attention and hold it long after waking.

Thirdly, a few MemD themes relate closely to the prominent themes of children’s dreams generally, with more animals and higher family references.  As I noted earlier, the SDDb baseline for MemDs includes numerous childhood-era dreams reported by children and adults, so it is definitely skewed toward children’s dream content.  That means the differences between MRDs and MemDs could be explained as artifacts of the differences between adults and children.  I grant there will be a large degree of overlap between highly memorable dreams and children’s dreams–precisely because the most memorable dreams people often recall are dreams from childhood.

Not all children’s dreams are big dreams–but many big dreams are dreams that have been remembered from childhood.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Animals in Dreams

Below is the section on animal dreams from my video talk for the IASD Australian Regional Conference held last week in Sydney.  I would be very interested in hearing from people whose dreams include types of animals NOT mentioned in my findings, to help us develop an even broader sense of oneiro-zoology (yes that’s a made up word!).

 

Animals: I searched the SDDb for many different types of animal-related words, but I’m sure I missed some, so this is an area needing improvement.  What I found in this study [of 2087 total dreams, 1232 female and 855 male] was 16% of the female reports and 14% of the male reports including at least one animal reference.  Consistent with what previous researchers have found, the children’s dreams in my sample have a higher percentage of animal references (24% for the girls, 20% for the boys).  Does this mean children are “closer” to nature than adults?  Perhaps.  It does seem that a higher proportion of animals in children’s dreams (or should we say a diminished proportion of animals in modern Western adults’ dreams?) is a stable pattern across many studies.

The animals that appeared most often were, in order, dogs, cats, horses, bears, fish, snakes, birds, and insects.  The first three—dogs, cats, and horses—are among the most familiar domestic animals.  Bears are NOT domestic animals, and they actually appear most often to be aggressive, threatening creatures in dreams.  Among different types of fish, sharks appear frequently like bears, as frightening predators, putting the dreamer in the harrowing position of prey, the hunted.  In other dreams, however, ocean dwelling creatures like whales and dolphins reveal an amazing intelligence that teaches the dreamer something new about the natural world.
