What Are the Ethics of Dreaming?

When people think about ethics, they usually focus on the evaluation of good or bad behaviors in the waking state. But what about the ethical status of the one-third of our lives that we spend in sleep? Do we have any ethical duties or obligations relating to sleep? Do dreamers have any basic rights or responsibilities?

Many people treat dreaming as a kind of ethical “free-fire zone,” where moral boundaries don’t apply and anything goes. The ancient Greek philosopher Plato said that when we sleep the “rational, gentle, and dominant” part of the mind retires, unleashing the “beastly and savage” parts, leading to the outrageous immorality of dreaming: “there is nothing it will not venture to undertake as being released from all sense of shame and all reason.” (The Republic, book IX) More recently, some enthusiasts of lucid dreaming have encouraged using conscious dream control as a tool to enjoy consequence-free fantasies of sex and power. Dreaming in this view is reduced to the ethical status of a video game, where nothing is “real” and the players can behave however they wish.

In both of these cases, dreaming is cast outside the sphere of normal ethics. Sleep and dreaming are treated as sub-human realms where ordinary moral rules do not apply.

Several problems follow from this view, to be explored in future posts. Here, we’ll consider one particularly urgent problem. Think of it like this: In regular waking life, if someone tricked you into do something you didn’t want to do, we would call that other person’s action unethical. But does that judgment change if it happens in your dreams? If the person tricks you into having a dream of something you otherwise would not dream about, can we still call their action unethical? It seems not, according to the prior view that nothing that happens in dreaming really matters. Where’s the harm? Where’s the negative impact? They might have forced you to have a dream, but all dreams are unreal, so what exactly did they force you to do? When we start with the assumption that dreaming is a moral wasteland and ontological void, it becomes more difficult to draw appropriate ethical lines around waking behaviors that have effects on people’s capacity for dreaming.

This is not a theoretical concern. Thanks to new technologies in data science and brain imaging, researchers are now able to identify meaningful patterns in dream content with unprecedented speed and accuracy. That’s not a problem—new knowledge is a good thing! The problem comes with the unethical use of that knowledge to manipulate other people’s dreams without their awareness or full understanding. The increasing availability of these technologies makes it easier to attempt such manipulations for political, commercial, or criminal purposes.

It may seem paradoxical, but support for a higher ethical status for dreaming comes from current scientific research on dreams. Findings in neuroscience and cognitive psychology show that the brain processes our experiences in dreams very much like it processes our experiences in waking life. The vivid realism of dreaming is deeply rooted in the regular workings of the neural networks of our brains, with potentially strong and long-lasting effects on the waking mind in the form of “big dreams,” which have been reported throughout history and across all cultures. Modern dream researchers are helping us understand more clearly than ever before that 1) the dreaming mind is closer to the waking mind than Plato’s “wild beast” model suggests, and 2) dream experiences are more neurologically real and personally impactful than the “video game” model suggests.

Of course, Buddhists have long taught that karmic traces can accumulate in sleep, so you shouldn’t think you can break the precepts while dreaming and get away with it. Christian theologians like Augustine and Aquinas have argued that if people consent to immoral behavior in their dreams, their souls are indeed responsible for those sins. Modern researchers are simply adding empirical evidence and a neuro-cognitive framework to confirm this perennial insight about the ethics of dreaming.

New Dream Research in 2019

Dreaming, play, theater, science, religion, social and political crisis.

Jung, Freud, Shakespeare, a troupe of immigrant artists, Alice in Wonderland, Lucrecia de Leon, the US President.

These are the topics and the people I will be discussing most frequently in a series of presentations lining up for 2019. Each presentation will speak directly to the interests of a particular audience, and each one will also connect to the other talks I’m giving in ways that I hope will lead to a greater interwoven whole.

(All of these conferences and gatherings are still in the planning stages, so details may change.)

Society for Psychological Anthropology

Biennial Meeting, Santa Ana Pueblo, New Mexico

April 4-7

This will be part of a panel on “New Directions in the Anthropology and Psychology of Dreaming” organized by Robin Sheriff and Jeannette Mageo.

“Dreaming, Play, and Social Change”

This presentation offers a novel theory of dreaming—as a highly evolved form of play—and discusses its implications for new research in psychology and anthropology. The theory integrates findings from evolutionary biology, neuroscience, psychoanalysis, religious studies, and developmental psychology (especially D.W. Winnicott). This approach moves beyond the fruitless debates over the “bizarreness” of dreaming. From the play perspective, bizarreness in dreaming is a feature, not a bug. In dreams the mind is free to play, to explore, imagine, and envision new possibilities beyond the limits of conventional reality. Of special interest to anthropologists, the content of dreams, i.e., what people playfully dream about, mostly revolves around social life. Many of the cognitive abilities vital to waking sociality are also present in dreaming, which correlates with research showing that dream content accurately mirrors people’s most important waking relationships. In some instances, dreaming goes beyond mirroring the social world to actively striving to transform it; the playfulness intensifies, and the dreaming imagination labors to create something new, to go beyond what is to imagine what might be. This visionary potential is often activated during times of social conflict and crisis. Three brief examples will illustrate the playful dynamics of dreaming in relation to a crisis in the dreamer’s community: 1) the prophecies of Lucrecia de Leon, a young woman from 16^th century Spain; 2) the creatively inspiring “big dreams” of a group of immigrant artists; and 3) the politically-themed dreams of present-day Americans about their current President.

International Association for the Study of Dreams

Regional Conference, Ashland, Oregon

May 31 to June 2

This is the general description of the event, which I am helping to host with Angel Morgan. On Saturday morning I will give a talk on the role of dreams in Shakespeare’s “Macbeth” and Lewis Carroll’s “Alice in Wonderland,” both of which will be performed that weekend at the Oregon Shakespeare Festival.

“Theater, Dreams, and Art”

Shakespeare wrote “All the world’s a stage” and Carl Jung wrote that a dream is theater in which the dreamer is the scene, player, prompter, producer, author, public, and critic. The best plays are like the best dreams: surprising, decentering, mind-expanding, awe-inspiring, emotionally exhausting, and acutely memorable. They are unreal, yet realer than real; retreats into fantasy that catapult us into fresh engagement with the world. Many talented artists, as well as everyday creative people, have said they feel the same kind of freedom to explore their emotions in dreams that they do when they have an encounter with the artistic process. Many often connect the two by first logging their dreams, then drawing on the raw emotional content and imagery from their dream experiences to feed their art. That said, bridging dreams with theater and art tends to offer a wide variety of fascinating approaches. In this conference we hope to inform and inspire dreamers of all ages and backgrounds, as well as those who use theater, dreams, or art in their work, such as: parents, psychologists, therapists, counselors, writers, actors, directors, dancers, visual artists, and musicians.

International Association for the Study of Dreams

Annual Conference, Kerkrade, the Netherlands

June 20-26

This is part of a panel I am organizing with Svitlana Kobets and Bernard Welt on “Visionary Dreams in Art, Religion, and History.”

“Vision and Prophecy in the Dreams of Lucrecia de Leon”

This presentation explores the visual imagery, religious symbolism, and prophetic warnings contained in the dreams of Lucrecia de Leon, a young woman from 16^th century Madrid who was persecuted by the Spanish Inquisition as a traitor and heretic, despite the fact that many of her dream warnings came true.

This is part of a panel Jayne Gackenbach is organizing on the interplay of artistic practice and scientific inquiry.

“Dreaming Is Play: A Bridge Between Art and Science”

This presentation offers a theory that dreaming is a kind of play, the imaginative play of the mind during sleep. This theory has directly inspired me in new activities with art and artists: supporting regional theater, collaborating with the Dream Mapping Troupe, and cultivating a forested dream library.

American Academy of Religion

Annual Conference, San Diego, California

November 23-26

This is a “call for papers” topic that will soon be posted by the Cognitive Science of Religion (CSR) group of the American Academy of Religion, and open for submissions from all AAR members. If the CSR steering committee receives enough good proposals on this topic, there will be a panel session at the conference in San Diego with three or four presentations.

“Cognitive Science of Religion (CSR) Approaches to Dreaming”

The rise of psychology of religion in the early 20^th century was driven in part by Freud’s and Jung’s efforts to understand the nature of dreams. What would a new 21^st century approach to dreams look like, using the resources of CSR? Specifically, to what extent do cognitive functions known to operate in religious contexts (e.g., memory, imagination, metaphor, teleological reasoning, social intelligence, agency detection, dual-systems cognition) also operate in dreaming? To what extent does this shed new light on the various roles that dreams have played in the history of religions (e.g., theophany, healing, prophecy, moral guidance, visions of the afterlife)? Proposals are welcome that draw together detailed accounts of religiously significant dreaming with specific CSR concepts and theories.

The Science of Dreaming: 9 Key Points

The most important findings of scientific dream research can be summarized in nine key points. Many important questions about dreaming remain unanswered, but these nine findings have solid empirical evidence to support them.

Rapid eye movement (REM) sleep is a trigger for dreaming, but is not identical with dreaming. All mammals have sleep cycles in which their brains pass through various stages of REM and non-REM sleep. Dreaming seems to occur most often, and most intensely, in REM sleep, a time when many of the brain’s neuro-electrical systems have risen to peak levels of activation, as high as levels found in waking consciousness. However, dreaming occurs outside of REM sleep, too, so the two are not identical; REM sleep is neither necessary nor sufficient for dreaming.
REM helps the brain grow. The fact that REM sleep ratios are at their highest early in childhood (newborns spend up to 80% of their sleep in REM, whereas adults usually have 20-25% of their sleep in REM) suggests that REM, and perhaps dreaming, have a role in neural maturation and psychological development.
Dreaming also occurs during hypnogogic, hypnopompic, and non-REM stage 2 phases of sleep. In the transitional times when a person is falling asleep (hypnogogic) or waking up (hypnopompic), various kinds of dream experiences can occur. The same is true during the end of a normal night’s sleep cycle, when a person’s brain is alternating exclusively between REM and non-REM stage 2 phases of sleep, with a relatively high degree of brain activation throughout. Dreams from REM and non-REM stage 2 are difficult to distinguish at these times.
The neuro-anatomical profile of REM sleep supports the experience of intense visionary imagery in dreaming. During REM sleep, when most but not all dreaming occurs, the human brain shifts into a different mode of regional activation. Areas of the prefrontal cortex involved in focused attention and rational thought become less active, while areas in the limbic system (involved in emotional processing, memory, and instinctive responses) and the occipital lobe (involved in visual imagination) become much more active. This suggests that the human brain is not only capable of generating intense visionary experiences in dreaming, it has been primed to do so on a regular basis.
The recurrent patterns of dream content are often continuous with people’s concerns, activities, and beliefs in waking life. This is known as the “continuity” hypothesis, and it highlights the deep consistency of waking and dreaming modes of thought. People’s dreams tend to reflect the people and things they most care about in the waking world. A great deal of dream content involves familiar people, places, and activities in the individual’s waking life. The dreaming imagination is fully capable of portraying normal, realistic scenarios. This means dreaming is clearly not a process characterized by total incoherence, irrationality, or bizarreness.
The discontinuities of dreaming, when things happen that do not correspond to a normal waking life concern, can signal the emergence of metaphorical insights. Research on the improbable, unreal, and extraordinary elements of dream content has shown that, on closer analysis, this material often has a figurative or metaphorical relationship to the dreamer’s waking life. Metaphorical themes and images in dreams have a long history in the realm of art and creativity, and current scientific research highlights the dynamic, unpredictable nature of dreaming as an endless generator of conceptual novelty and innovation.
Dream recall is variable. Most people remember one to two dreams per week, although the memories often fade quickly if the dreams are not recorded in a journal. On average, younger people tend to remember more dreams than older people, and women more than men. Even people who rarely remember their dreams can often recall one or two unusual dreams from their lives, dreams with so much intensity and vividness they cannot be forgotten. Dream recall tends to respond to waking interest. The more people pay attention to their dreams, the more dreams they are likely to remember.
Dreaming helps the mind to process information from waking life, especially experiences with a strong emotional charge. From a cognitive psychological perspective, dreaming functions to help the mind adapt to the external environment by evaluating perceptions, regulating emotional arousal, and rehearsing behavioral responses. Dreaming is like a psychological thermostat, pre-set to keep us healthy, balanced, and ready to react to both threats and opportunities in the waking world. Post-traumatic nightmares show what happens when an experience is too intense and painful to process in a normal way, knocking the whole system out of balance.
The mind is capable of metacognition in dreaming, including lucid self-awareness. During sleep and dreaming the mind engages in many of the activities most associated with waking consciousness: reasoning, comparing, remembering, deciding, and monitoring one’s own thoughts and feelings. Lucid dreaming is one clear example of this, and so are dreams of watching oneself from an outside perspective. These kinds of metacognitive (thinking about thinking) functions were once thought to be impossible in dreaming, but current research has proven otherwise. Dreaming has available the full range of the mind’s metacognitive powers, although in different combinations from those typically active in ordinary waking consciousness.

Recent Interviews About “Big Dreams”

In the past couple of weeks I have spoken several times with journalists about Big Dreams: The Science of Dreaming and the Origins of Religion. It’s a daunting experience to have smart people read what you’ve written and ask sharp questions about how you put together your argument… and all the more intimidating with a tape recorder running. But I think the basic ideas from the book come through pretty well in these pieces. Continue reading “Recent Interviews About “Big Dreams””

The Origins of Religion in Dreaming

One of the oldest theories about the origins of religion argues that religious beliefs and practices are derived from the experience of dreaming. This theory is most often associated with the 19^th century British anthropologist E.B. Tylor, as expressed in this passage from the 1873 work Primitive Culture:

“The evidence of visions corresponds with the evidence of dreams in their bearing on primitive theories of the soul, and the two classes of phenomena substantiate and supplement one another….That this soul should be looked on as surviving beyond death is a matter scarcely needing elaborate argument. Plain experience is there to teach it to every savage; his friend or his enemy is dead, yet still in dream or open vision he sees the spectral form which is to his philosophy a real objective being, carrying personality as it carries likeness.”

This same idea was also expressed, in even sharper language, by the German philosopher Friedrich Nietzsche just a few years later, in his 1880 book Human, All-Too Human:

“Misunderstanding of the dream. –The man of the ages of barbarous primordial culture believed that in the dream he was getting to know a second real world: here is the origin of all metaphysics. Without the dream one would have had no occasion to divide the world into two. The dissection into soul and body is also connected with the oldest idea of the dream, likewise the postulation of a life of the soul, thus the origin of all belief in spirits, and probably also of the belief in gods. ‘The dead live on, for they appear to the living in dreams’: that was the conclusion one formerly drew, throughout many millennia.”

I have just finished writing the manuscript for a book that tries to put this idea to the scientific test. The book is titled Big Dreams: The Science of Dreaming and the Origins of Religion, and it will be published by Oxford University Press later this year or early next. The basic thesis is that Tylor, Nietzsche, and others are right, dreaming is indeed an experiential source of religious beliefs and practices, and the best evidence from cognitive scientific research backs them up.

Rather than trying to give an all-encompassing theory of religion, I focus on a few specific areas of religious experience where dreams play an especially influential role: demonic seduction, prophetic vision, ritual healing, and contemplative practice. The title of the book draws on psychologist C.G. Jung’s notion of “big dreams” as rare but extremely vivid dreams that make a strong and lasting impression on waking awareness. I use resources from traditional psychology of religion (e.g., William James, Sigmund Freud) as well as from newer works in the cognitive science of religion (e.g., Emma Cohen, Harvey Whitehouse, James W. Jones) as guides in applying scientific dream research to the study of religion.

This is also the first book I’ve written using the Sleep and Dream Database (SDDb) as a primary resource. I’m just learning how to use the digital tools of the database myself (an upgraded version of the site will come online in the next few days), and the more SDDb analyses I did for this book, the more excited I became about possibilities for future projects in data-driven dream research that look at religious and cultural phenomena with fresh, empirically curious eyes.

Digital Dream Analysis: A New Article on Word Search Methods

The latest issue of the journal Consciousness and Cognition has an article of mine titled “Digital dream analysis: A revised method,” that’s the fruition of several years of data-driven work. It lays out the latest developments in testing and refining the word search template programmed into the Sleep and Dream Database, a digital archive and search engine designed to promote scientific dream research. The original article I wrote using this word search method was in a 2009 issue of Consciousness and Cognition, titled “Seeking patterns in dream content: A systematic approach to word searches.” The new article builds on that earlier piece and extends it in two ways.

First, it presents a revised, 2.0 version of the word search template that has many improvements on the 1.0 version presented in the 2009 article. I’m sure there will be more refinements in the future, and hopefully more researchers developing their own templates as well. But for now, the 2.0 version is useful as a well-tested and fairly comprehensive tool for analyzing dream content simply, quickly, and reliably.

Second, the article applies the 2.0 word search template to a number of previously studied collections of dreams from very high quality sources (Calvin Hall and Robert Van de Castle, J. Allan Hobson, and G. William Domhoff). In doing so I followed the advice of Kurt Bollacker, database engineer for the SDDb, who suggested I take “classic” studies in dream research from the past and try applying my new method to their same data. That’s what I have done in this article: use the word search method to analyze the same sets of dreams those researchers studied, so we can see what the new method can and cannot tell us about meaningful patterns in dream content.

Here is the abstract for the article. The whole thing, I’m told, is available for free download until November 22, 2014.

“This article demonstrates the use of a digital word search method designed to provide greater accuracy, objectivity, and speed in the study of dreams. A revised template of 40 word search categories, built into the website of the Sleep and Dream Database (SDDb), is applied to four “classic” sets of dreams: The male and female “Norm” dreams of Hall and Van de Castle (1966), the “Engine Man” dreams discussed by Hobson (1988), and the “Barb Sanders Baseline 250” dreams examined by Domhoff (2003). A word search analysis of these original dream reports shows that a digital approach can accurately identify many of the same distinctive patterns of content found by previous investigators using much more laborious and time-consuming methods. The results of this study emphasize the compatibility of word search technologies with traditional approaches to dream content analysis.”
