New Dream Posts from Psychology Today

Here are the recent posts I have written for Psychology Today, going back to the middle of last summer. Although each one is written as a stand-alone discussion of a special topic in dreaming, I now realize they also form a series of interrelated texts, like the chapters of a book I didn’t consciously know I was writing….

The Ethical Challenges of Dream Video Technologies

New technologies are making it possible to use brain data to create video reconstructions of people’s dreams while they sleep. Is this thrilling, terrifying, or both?

Here’s how it works. Researchers are learning how to observe an individual’s brain while viewing a specific image (let’s say a cat) and how to identify neural patterns correlated with that image. Then the researchers observe the individual’s brain while sleeping, and watch for a recurrence of the “cat” neural pattern. If it appears, a signal can be sent to a video monitor to show an image of a cat—presumably what the sleeping person is dreaming about at that very moment.

Does this mean we will soon be able to sit in front of a “dream-viewer” (an iDreamer?) to watch videos of our own dreams, along with the dreams of other people?

Soon, probably no. But someday, possibly yes. Many technical challenges have to be overcome first. Lots of time and effort are required to train the computer algorithms to recognize the patterns of an individual’s brain. The patterns for “cat” from one person’s brain do not necessarily match the “cat” patterns from another person’s brain, so the system has to be trained and calibrated anew for each individual.  The nearly infinite variety of dream content magnifies the learning challenge for this kind of technology (how many images of different kinds/colors/sizes of cats need to be incorporated into the system?). Efforts to model the contents and experiential qualities of dreams have to find some way to reckon with a boundless, unpredictably varied set of data.

Advocates will emphasize the potential benefits if these methodological challenges can be overcome. Researchers would, for the first time, have “objective” dream data, unfiltered by the subjective biases and limited memories of the dreamer. For anyone who looks to dreams for personal insight and guidance, this technology offers a quantum leap in the depth and range of access to one’s dreaming experience. For example, psychotherapists would have a powerful new resource for understanding the unconscious conflicts, fears, and concerns of their clients.

All of these potentially positive applications sound appealing, of course. But no less time should be given to considering the potentially negative applications, too. Between now and the invention of a true “dream-viewer,” we should consider several ethical questions raised by this technology.

Does the process of training and calibrating the system disrupt the natural rhythms of people’s sleep and dreams? If yes, what are the long-term health risks and psychological dangers of that disruption? This basic question is too rarely asked in discussions of new dream technologies, perhaps because of an unspoken assumption that dreams themselves aren’t really “real,” so nothing that harms dreaming does any real harm to a person.

What is the source of the images used to reconstruct people’s dreams? Who chooses those images? Is there transparency in the algorithms that correlate specific images to specific neural patterns? Are measures taken to prevent biases from excluding the appearance of certain kinds of images and favoring others?

Does the technology distort and flatten the contents of people’s dreams? It seems likely a dream-viewer will be incapable of representing bizarre or anomalous experiences for which there are no images. It will struggle to represent essential elements of dreaming like feelings, thoughts, and bodily sensations. It won’t be able to convey non-imagistic qualities of intensity, atmosphere, or awareness. Jorge Luis Borges noted these qualities when he described a nightmare of an ancient King standing by his bed: “Retold, my dream is nothing; dreamt, it was terrible.” (Seven Nights, 1980) Will a dream-viewer ever be able to convey the ineffable terror in a nightmare like the one Borges experienced? It seems unlikely. Videos will show what videos show, not what dreams are in any full or objective sense.

Who gets access to the dream-viewers? What is done with this incredibly personal source of information? It takes little imagination to envision potential abuses of this technology for commercial, political, governmental, and/or criminal purposes. The prospect of bad actors gaining access to private details so secret even the individual does not consciously know them should be a red-flag concern for any technology that is openly offering an unfiltered view into people’s dreams.

Can this technology be re-engineered to manipulate the process and contents of dreaming itself? What if a tool designed to identify neural patterns associated with dreaming could be re-purposed to selectively target specific patterns either for suppression or stimulation? This seems to lead into Inception territory, making people vulnerable to an unprecedented depth of external control and manipulation.

How much dream awareness can people handle? An earlier and even more direct film reference to this kind of technology appears in Wim Wenders’ futuristic film Until the End of the World (1991), in which the equivalent of a dream-viewer has been invented. The CIA is determined to steal the device, which of course is not a fantastical idea at all. If and when a dream-viewer is created, CIA interrogators would surely be at the front of the line to get one. More unexpectedly, the characters in the movie who use the device become lost in the narcissistic labyrinths of their own fantasies. They detach from the rest of the world, retreating into a video womb of reconstructed dreaming. Here, the technology’s danger is not from abuse by others, but from our own abuse of it. We assume that more insight into our dreams is a good thing, but is that true for everyone? Do each of us have a healthy limit of dream awareness, beyond which we become lost in ourselves?

Final Thought

Dreaming is an innate function of the brain-mind during sleep. It is also an experience that humans from around the world and all through history have considered vitally important, meaningful, and useful in their waking lives. Any new technology that has the potential, whether intended or not, to disrupt the natural rhythms of people’s sleep and dreaming needs to be publicly evaluated in terms of its long-term risks and benefits.

The Best Technology for Studying Dreams

It’s hard to beat the simple practice of keeping a dream journal.

Many exciting new tools are being developed to help us understand the nature and functions of our dreams. For example, researchers are developing technologies for generating a video “read-out” of a person’s dreams based on neural signals from the brain. They are devising methods to stimulate a sleeping person’s brain to instigate lucidity or consciousness during a dream, or even to prompt certain kinds of dream content.

However, none of these new technologies are as valuable for the study of dreams as one of the simplest tools available: the dream journal. A record of an individual’s dreams over time offers the most powerful tool we currently have for the study of dreams. Even compared to the most high-tech devices used by neuroscientists, the dream journal has big advantages in effectiveness, accessibility, and privacy.

Effectiveness

The new dream technologies mentioned above have very short track records. We still don’t know many details about their impact on brain functioning during sleep, nor do we know how the impact varies according to individual differences among people from across the demographic spectrum. And, all these tools rely on measurements of neural activity that have to be interpreted by the researchers and translated into meaningful mental content. That’s not an easy or purely objective process.

However, dream journals as a tool of studying and exploring dreams has a very long track record, going back many centuries (The Sacred Tales of Aelius Aristides in the 2nd century may be the oldest surviving example). We know from extensive psychological research that recording one’s dreams over time yields rich personal insights and self-knowledge. Psychologists have used dream journals starting with Freud’s own dreams in The Interpretation of Dreams, and continuing through Allan Hobson’s use of the “Engine Man’s” dreams in The Dreaming Brain, and now to the works of G. William Domhoff, Michael Schredl, and others who find that dream journals provide legitimate scientific insights into recurrent patterns of content. Only by tracking an individual’s dreams over time can these patterns be identified. Both for psychologists doing research and individuals seeking personal growth, the dream journal remains the most effective technology available.

Accessibility

The new dream technologies are generally used in hospitals or research laboratories. Some devices have been developed for home use, but they tend to be expensive and complicated to operate. Extensive training and preparation are required for the use of these tools, along with a sophisticated computer system and a reliable internet/electrical system. All of these factors have limited the accessibility of new dream technologies to a very small number of people.

The dream journal, by contrast, is available to virtually everyone. To keep a dream journal, you need no training or special preparation, and you don’t have to go to a laboratory or hospital. All that is required is a method of recording your dreams (e.g., by pen and paper, computer, voice-to-text), and a safe place to preserve them over time. This makes the dream journal by far the most accessible tool for studying dreams.

Privacy

Almost every type of new dream technology has connections to the internet that feed data from individual dreamer to the researchers and back again. Even if the researchers preserve the confidentiality of the individual’s data, which of course they should, the sheer presence of an outside observer peering into one’s dreaming experiences and reflections naturally heightens people’s concerns about personal privacy. Some of the new technologies, for example the dream-visualization tools and the dream-altering tools, clearly raise enormous ethical issues around protecting the privacy and integrity of one’s inner thoughts.

A dream journal has the advantage here of being a type of personal diary. Just as a diary provides a safe and private space for honest self-reflection, a dream journal offers the same kind of private space for exploring one’s dreams. A dream journal “works” as a tool without anyone else’s input. All you need is you, paying attention to your own dreams consistently over time. You can keep the results to yourself, and no one else needs to know anything about what you are doing.

None of this is to dismiss the exciting potentials of many new technologies to improve our understanding of dreams and perhaps even enhance our experience of dreaming in a meaningful way. But the enduring power and simplicity of the dream journal, and its advantages in effectiveness, accessibility, and privacy, suggests that a good strategy for new technologies is to build on the dream journal, amplifying what it can already do. Any new dream technology will be stronger if it is grafted onto a solid dream journal system as its roots.

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.

Nightmares of a Smart Home

Dreams from Germans in the 1930’s highlight the danger of new home technologies.

I have always been a strong advocate for the creative potentials of dreaming and its capacity to envision future realities. Now, however, I worry that dreams from an earlier era may have predicted a new technology with frightening potentials for abuse in our world today.

One of the most important books in 20th century dream research was The Third Reich of Dreams by Charlotte Beradt, published in English in 1968. Beradt was a journalist in Germany, and when the Nazis rose to power she, as a Jew, could no longer find work. Instead, from 1933 until 1939, when she and her husband fled Germany to the United States, Beradt collected people’s dreams about the Nazis. She cast a wide net among friends and acquaintances, asking for dreams about their country’s increasingly dire political situation. The resulting book was not only searing testimony of the psychological brutality of the National Socialist regime. It also illustrated how dreams can accurately reflect collective fears during times of social crisis.

Many researchers have been deeply moved by The Third Reich of Dreams and inspired to explore new ways of drawing cultural insights from individual dreams. When I first encountered Beradt’s book in the 1980’s during graduate school, I was struck by the poignant reflections in these dreams of people’s experiences in an increasingly totalitarian environment where “others” were attacked as inhuman, racial purity and blind loyalty were exalted, and no one could escape the pervasive atmosphere of fear and vulnerability.

I was especially intrigued by a type of dream that Beradt described as the ultimate example of political toxicity. These were nightmares in which the oppressive power of the state reached directly into people’s homes and turned their own possessions against them. From a woman described as a housewife, in 1933:

“A Storm Trooper was standing by the large, old-fashioned, blue-tiled Dutch oven that stands in the corner of our living room, where we always sit and talk in the evening. He opened the oven door and it began to talk in a harsh and penetrating voice. It repeated every joke we had told and every word we had said against the government. I thought, ‘Good Lord, what’s it going to tell next—all my little snide remarks about Goebbels [Nazi Minister of Propaganda]?’ But at that moment I realized that one sentence more or less would make no difference—simply everything we have ever thought or said among ourselves is known.” (45)

Reading Beradt’s commentary on this dream today sounds eerily prescient, and uncomfortably resonant with current concerns about new home technologies. Remember, she was writing more than fifty years ago, about events that happened thirty years before that:

“Here we see a person in the process of being fashioned by a very elusive and even today not fully understood form of terrorization, a terrorization that consisted not of any constant surveillance over millions of people but rather the sheer uncertainty about how complete this surveillance was…. What dream could better suit the purposes of a totalitarian regime?” (47)

She went on:

“A greengrocer had exactly the same type of dream about a cushion he placed over the telephone when the family gathered in the evening for a cozy chat, a precaution everyone took in those days. The atmosphere of coziness became one of terror: the cushion—a sentimental keepsake cross-stitched by his mother and ordinarily kept in his easy chair, his domestic throne—began to talk. It testified against him and went on and on, repeating family conversations ranging from the price of vegetables and the midday meal to the comment ‘Old Potbelly [Hermann Goering, Nazi Party leader] is getting fatter by the day.’” (49)

Such dreams expressed a catastrophic loss of privacy and safety, even within the personal confines of one’s own home. Objects which used to give people pleasure and comfort now turned against them and became their enemies. She continued:

“I received quite a few reports about similar dreams involving household objects—about a mirror, a desk, a desk clock, an Easter egg. In each of these cases, all that remained in the recollection was the fact that the object concerned would denounce people. The frequency of such dreams may have increased as people became more and more aware of the methods the regime employed.” (49)

Beradt did not rely on any psychological theories in her approach to these dreams. Indeed, she did not try to interpret the dreams at all, at least in a conventional sense. Rather, like the journalist she was trained to be, she focused on reporting the cases that gave the most vivid illustrations of life in a totalitarian society. She used the political ideas of Hannah Arendt and George Orwell (especially his novel 1984) as guides in connecting the personal dream imagery to collective political realities.

“The following singularly grotesque example of this type of dream was dreamt by a young girl: ‘I dreamt I awoke in the middle of the night to discover that the two cherubs that hang over my bed were no longer looking upwards but were instead staring down at me. I was so frightened that I crawled under the bed.’” (50)

These nocturnal visions from another place and time offer an uncanny foreshadowing of present-day anxieties about the dystopian dangers of new household technologies. It takes no great leap of imagination to see connections between Beradt’s haunting collection of dreams and the latest generation of “smart” lamps, appliances, thermostats, and the like. People are inviting into their homes devices that were the stuff of surreal nightmares in Nazi Germany. The marketing for Amazon’s Alexa, Google’s Assistant, and Apple’s Siri emphasize their power to relieve us of domestic toil, increase our comfort, and save us money. And yet, despite the many benefits of these systems, recent reports (here, here, here, and here) have shown how easily they can be abused in exactly the ways foreseen by Beradt’s dreamers—secretly recording private conversations and revealing embarrassing, immoral, and incriminating behavior.

For people living in Germany in the 1930’s, their futuristic dreams of smart devices reflected a terrifying realization of the intrusive power of the state and its dominance over the most intimate personal aspects of their lives. The challenge today is preventing their nightmares from becoming our realities.

What Kinds of Technology Do People Dream About Most Frequently?

50.ford_.crestlinerThe past one hundred years of human history have been dramatically transformed by the invention of several new technologies, each of which has impacted people’s lives in profound and complicated ways.

In light of empirical research showing strong continuities between waking and dreaming, we can hypothesize that modern technologies have also made a tangible impact on the content of people’s dreams.

And indeed, there is evidence in support of that idea. By analyzing a collection of more than 16,000 dream reports available for study on the Sleep and Dream Database (SDDb), it becomes possible to examine which kinds of technology have most influenced people’s dreams in terms of their frequency of appearance.

The results suggest the newest technologies are not necessarily the most important ones in the world of dreams.

To explore this question I looked at all the dream reports on the SDDb of 25 words or more in length for Females (N=10,168) and Males (N=6,590), and selected the “Technology and Science” category from the 2.0 word search template.

This is a quick and dirty approach, but it has the virtue of providing an easy and relatively straightforward means of getting an evidence-based response to the question.

The results for the Females were 990 dream reports with at least one reference to a word in the “Technology and Science” category, approximately 10% of the total number of dreams. The figures for the Males were 602 and 9%.

Looking in more detail at which terms appeared most frequently (these include singular and plural uses of the term), the results for the Females were these:

Phone, 3.55%

Movie, 3.18%

Video, 1.26%

Computer, 1.2%

Machine, .91%

Radio, .65%

Camera, .62%

Television, .26%

And for the Males:

Phone, 2.69%

Movie, 2.47%

Video, 1.27%

Computer, 1.03%

Machine, 1.02%

Radio, .47%

Camera, .49%

Television, .36%

I did a parallel search with the same two sets using the SDDb 2.0 word search template category for Transportation. These results—24% of the dream reports for both Females and Males had at least one reference to a Transportation word—are much higher than the Technology and Science frequencies.

Looking more closely at specific forms of transportation appearing in people’s dreams, these were the results for the Females:

Car, 9.12%

Boat, 1.92%

Bus, 1.81%

Airplane, 1.49%

Truck, 1.26%

Elevator, 1.16%

Bicycle, .86%

And for the Males:

Car, 8.18%

Boat, 2.12%

Bus, 1.65%

Bicycle, 1.56%

Airplane, 1.46%

Truck, 1.37%

Elevator, .67%

The first thing to note is the remarkable gender balance. On almost all the categories and word clusters, the Female and Male frequencies are extremely close. (The main exceptions are slightly more Bicycle references for the Males, and slightly more Phone, Movie, Car, and Elevator references for the Females.) This consistency across so many terms suggests that modern technologies have impacted men and women about equally.

Secondly, the analysis indicates that the most frequently appearing modern invention in dreams is the automobile. It seems that technologies of transportation have had more of an impact on people’s dreams than have technologies of communications and entertainment.  Add in trucks and buses to cars, and the predominance of the internal combustion engine in dreaming becomes even greater.

Why might this be? I’m not sure, but I wonder if technologies of transportation have more of a visceral impact on people’s lives. Telephones, movies, videos, and computers can be fascinating and absorbing, but they do not directly affect a person’s body with the kind of sensory intensity that people feel during a car ride.

Whatever the explanation, the results of this brief study indicate that the most frequently appearing type of modern technology in dreams is one that was invented more than one hundred years ago. Newer technologies like computers and videos have not (yet) made as big an impression on the dreaming imagination.

Maybe future developments in virtual reality will enable a more powerful stimulation of people’s physiological responses, prompting a rise in VR-related dreams. But that remains a far-off possibility.

Until then, cars remain for most people the dream technology of choice.
