Memories of Jeremy Taylor

The world has just lost one of its greatest, wisest, and most compassionate dream teachers.  The Reverend Jeremy Taylor died two days ago, just two days after the death of his wonderful wife and life companion Kathy, a sage dreamer and artist herself.  Their passing together makes a tragic kind of sense, as an ultimate expression of their profound love for each other.  I miss them both deeply.

For more than fifty years, Jeremy has been traveling the country and the world, teaching people about dreams in an incredibly wide variety of places and circumstances.  I’m not sure any single person has devoted more of his life’s creative energy to the cause of increasing public awareness of dreaming.  And I’m not sure any single person has had a greater beneficial impact on the overall tenor and ethos of contemporary dream research.

It will take a long time to reflect on his legacy and take in the full scope of his influence.  What strikes me immediately is how he taught us to find the exciting potentials in even the tiniest dream fragment, and how he welcomed everyone, from all backgrounds, into the great spiritual adventure of exploring the world of dreaming.  He also taught us to think of dreaming as a window into social conflict and cultural change—an idea with more resonance than ever right now, as he well knew.

Below is the card he sent me on July 10, 1987, in response to my asking him for an opportunity to meet him and talk about his work.  I had just finished my first year in doctoral studies, and was trying to figure out where exactly I wanted to focus my research.  The meeting that ensued from Jeremy’s warm invitation (at 10 am at their home in San Rafael) had a direct impact on how my studies proceeded from there (he had published Dream Work in 1983).  And it all ties together in a way, because I first heard about Jeremy through my mother, who was working for a time with Kathy Taylor in Marin County and happened to mention my interests to her.  Kathy suggested I contact Jeremy, which I did.  And my life changed as a result.

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. 

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.

1,001 Nights of Dream Recall

Between January 8, 2015 and October 4, 2017, I remembered and recorded a dream every night for 1,001 consecutive nights.  Now I’m studying the dreams and trying to find insights that can help in exploring the dream series of other people.  I don’t expect anyone to accept my personal dreams as conclusive evidence for any general theory of human dreaming.  Instead, I offer them as way of being transparent about the experiential grounding of my research pursuits.  This is one of the ways I get ideas for new projects.

All of the dreams are available online for further study in the SDDb, in the “Sample Data” section.

From a scientific perspective, the value of an introspective project such as this is to generate working hypotheses for future studies.  Trying to study another person’s long diary of dreams can be very challenging, especially at the outset when the researcher is facing a huge mass of texts with multiple dimensions of meaning.  I appreciate anything that can provide some initial orientation and help to steer the direction of the analysis.  By studying my own dreams, which I know from both a first- and third-person perspective, I can quickly and easily identify some patterns of meaning that seem worth further exploration.   Maybe they will apply to someone else’s dream series, maybe they won’t; either way, it helps the analytic process get going.

Remembering and Recording the Dreams

The method I use for keeping my dream journal is fairly typical.  I keep a pad of paper and a pen by my bedside, and when I wake up in the morning I immediately write down whatever dreams I can remember, before getting out of bed or turning on the light.  Then later in the morning I type the dream into a digital file, along with associations, memories, and thoughts about what the dream might mean.

During the three years of recording this series of 1,001 dreams, I did my best to wake up slowly each morning, so the images and feelings from the preceding dreams could coalesce in my memory.  I don’t believe I dreamed more during this time than I did in previous periods of my life; rather, I devoted more energy to remembering the wispier, more evanescent kinds of dreams that, in previous years, had not crossed the threshold into waking memory.  I made a more determined effort to protect the space around the transition from sleeping to waking, even during circumstances when that was difficult to do (e.g., on international plane flights, during family holidays).  Often it took a few moments of quietly lying in bed with my eyes closed before the vague feeling “I know I was just dreaming,” could eventually take form into a specific memory of what I was just dreaming about.  Often there were “aha!” moments when suddenly a whole long dream came back to me, which I surely would have forgotten if I had immediately leapt out of bed upon awakening.

I also put more conscious intention into the other end of the transition, from waking into sleeping, as I carefully set up my journal and pen each night before turning out the light.  I did not set specific dream incubation questions during this time, but simply tried to signal to myself that I was ready and willing to record whatever dreams might come during that night’s sleep.

These were not extreme or burdensome behaviors; they required consistency of purpose, but no heroic feats of will.  I never set any long-term goals or numerical targets.  Instead, I just focused on each new night and each new dream, figuring the time would come when I could survey the series from a broader perspective.

About a month ago I finally did the math, and realized that October 4th would mark 1,001 nights of dream recall in a row, an enchanting milestone.  This seemed like a large enough collection of dreams to pause, look back, and see what I could learn.

Patterns of Word Usage

The reports comprise a total of 93,050 words, with an average length per dream report of 93 words, and a median length of 73 words.  The shortest dream in the series has 9 words, and the longest has 728 words.  The average length of these dreams is not unusual, compared to other people whose dreams have been analyzed in this way.  Some people have much longer dreams than I do, and some people have much shorter dreams.  This series of 1,001 dreams, then, includes mostly dreams of middling length.

To highlight the patterns and themes in a series like this, I start by comparing it to what I call the “SDDb baselines,” two large collections of male (N=2,135) and female (N=3,110) dreams that have been systematically gathered and analyzed using a template of 8 classes and 40 categories of word usage.   I use the baselines a measuring stick for identifying possible continuities and discontinuities between the dreams and the individual’s waking life.

The results of this comparative analysis are presented in an accompanying spreadsheet, “1001 Nights Data.”  Some of the discussion below draws on an earlier analysis I wrote about an overlapping set of my dreams.

In relation to the SDDb baselines (an average of 100 words per report for the females and 105 for the males), my dreams are a little shorter than average (93 words per report).  The results for each of the 8 classes of word usage are summarized below.  Compared to the male and female baselines, my 1,001 dreams have:

  1. Perception: More references to vision and colors.
  2. Emotion: Many more references to wonder/confusion, and more to happiness.
  3. Characters: Fewer references to family characters (although the word “wife” is mentioned very frequently), more references to animals (especially cats), and slightly more references to females than males.
  4. Social Interactions: Slightly more references to sexuality.
  5. Movement: Fewer references to death.
  6. Cognition: More references to thought, fewer to speech.
  7. Culture: Fewer references to school, food/drink, religion, somewhat more to sports (especially baseball and basketball).
  8. Elements: More references to water, somewhat more to earth.

These findings provide the basis for a “blind analysis,” which means making predictions about continuities between these patterns of word usage in dreaming and the individual’s waking life activities, beliefs, and concerns.  If I pretend I knew nothing about the dreamer of these 1,001 dreams, and I only had these word usage frequencies to consider, I would infer this individual:

  1. Is visually oriented
  2. Often experiences wonder/confusion
  3. Is relatively happy
  4. Is married
  5. Cares about cats
  6. Has fairly equal relations with men and women
  7. Is sexually active
  8. Is not concerned about death
  9. Is not highly verbal
  10. Is not highly involved with schools
  11. Is not highly concerned about food/drink
  12. Is not highly concerned about religion
  13. Has lots of interactions with water and earth

Most of these inferences—I’d say 11 of 13—are unmistakably accurate in identifying a continuity between a pattern of dream content and an aspect of my waking life concerns.  The two I would question are numbers 10 and 12.  Regarding the low frequency of dream references to school, I do in fact engage in a great deal of teaching and educational work, but it’s almost entirely online, and I rarely set foot inside a traditional school any more.  Also, I no longer have school-age children living at home.  So it seems my dreams are continuous with my physical behaviors relating to schools, but not with my computer-mediated educational activities.

Regarding the low frequency of religion references, I most certainly do have great interest in religion, going back to my masters and doctoral studies at the Divinity Schools of Harvard and University of Chicago.  So the inference seems very wrong at this level.  And yet, at another level it seems more accurate.  I was not raised in a religious household, I do not personally identify with any official religious tradition, and I rarely attend religious worship services.  Compared to other people I’ve studied with very high frequencies of references to religion in their dreams, I am a much less personally pious person.  Perhaps what this suggests is that the dreams are accurately reflecting the fact that religion may be an important intellectual category for me, but it is not a personal concern.  My spiritual pursuits are more likely to be expressed in dreams with references to other word categories like water, art, sexuality, animals, and flying.

Shorter versus Longer Dreams

Earlier this year I looked at different set of my dreams to get some idea about possible differences between shorter and longer dreams.  This question rose in relevance when I realized, as noted earlier, that my increased recall seemed to depend in part on the recollection of relatively shorter dreams that in the past I did not fully remember or write down.

There were two main findings of that earlier study.  First, most of the patterns in content appeared in dreams of all lengths, from the shortest (less than 50 words per report) to the longest (more than 150 words per report).  Here’s a summary of what I found:

“The results of this analysis suggest that shorter dreams are not dramatically different from longer dreams in terms of the relative proportions of their word usage.  The raw percentages of word usage do rise from shorter to longer dreams, of course, but the relative proportions generally do not.”

Second, the longer dreams did have proportionally more references to a few word categories, chiefly Fear, Speech, Walking/Running, and Transportation. Another quote:

“These are the word categories that seem to be over-represented in longer dreams.  They are significant contributors to what makes long dreams so long.”

Returning to the present collection of 1,001 dreams, I divided the series at the median point into two groups: the shorter dreams (72 words or less, 500 reports total) and the longer dreams (73 words or more, 501 reports total).  I used the same SDDb word searching template with each of the two groups as I used with the full series, and then I compared their frequencies of word usage.  The biggest variations between the shorter and longer dreams appeared in the following categories:

  • Touch
  • Fear
  • Anger
  • Physical aggression
  • Walking/Running
  • Speech
  • Transportation
  • Water

This list adds a few other categories that may be characteristic of longer dreams.  Each of these categories has a dynamic quality.  Touch is a physical interaction.  Fear and anger are strong and unpredictable emotions, usually prompted by something in the external environment.  Physical aggression combines the previous categories (touch, fear, anger) and possibly intensifies them.  Walking/Running and Transportation both involve physical movement from one place to another.  Speech implies a context of interpersonal communication, people talking with each other.  Water, the “universal solvent,” is ever-shifting in its states (gas, liquid, solid) and its movement through human life.

When these elements appear in my dreams they seem to have the effect of expanding the range of experience, stimulating more interactions, and lengthening the narrative.

Conclusion

I don’t know if any of this applies to anyone else’s dreams.  I do, though, believe that several of the insights gained here can provide working hypotheses for studying other series of dreams.  I will be keeping these ideas in mind as I explore new dream series:

  • The recall and recording methods of the dreamer influence the types of dreams included in the series.
  • Personal relationships are an area of especially strong continuity between waking and dreaming life.
  • The use of religion-related words in dreams may be discontinuous with spiritual interests in waking life.
  • Shorter dreams have mostly the same general proportions and patterns of content as found in longer dreams.
  • Longer dreams tend to include more dynamic elements.

A Guide to the Sleep and Dream Database

Just added to the SDDb library is A Guide to the Sleep and Dream Database, a text I hope will help to make the resources of the site more accessible to teachers, students, researchers, and anyone interested in dreams.

The guide is the first in a series of what I’m titling SDDb Research Papers.  This series will present new findings from projects that use the dream materials and analytic tools of the SDDb.  The papers will share works-in-progress in the empirical study of dreams.

Here is the abstract for the first paper:

Intended for newcomers to dream research, this guide offers an introduction to the functions of the Sleep and Dream Database (SDDb), an open-access digital archive that includes tens of thousands of dream reports, along with survey data about sleep, dreaming, and demographic variables.  Readers are shown how to use the Survey Analysis and Word Searching functions of the SDDb to study a variety of questions about dreaming.  The topics discussed here as illustrations include gender and age variables in dream recall; differences between men and women in the frequency of fear in their dreams; and the meaningful patterns of content in a woman’s long-term dream journal.

What the 2017 Nobel Prize in Medicine Means for Dream Research

This year’s Nobel Prize in Physiology or Medicine has an indirect but significant connection to dream research. For those of us who believe the scientific study of dreaming needs to be grounded in the evolutionary biology of sleep, the news of the 2017 Nobel should be a cause for celebration.

The prize was awarded to three Americans—Michael W. Young, Michael Rosbash, and Jeffrey C. Hall—in recognition of “their discoveries of molecular mechanisms controlling the circadian rhythm” (quoted from the Nobel committee’s public statement).  The key point, from a dream research perspective, is that these three investigators have shown we have a genetically hard-wired need to sleep.

All life on earth is fundamentally oriented toward the cyclical presence and absence of the sun. Every kind of living being has evolved internal clocks of approximately 24 hours in length that guide and regulate their biological processes and behaviors. These internal clocks are known as circadian rhythms, and they have long been observed as powerful factors in plant and animal life.  But only recently have the details of how these clocks work become known, thanks to the work of this year’s trio of prize winners.  Their studies, going back to the 1980’s, explain how circadian rhythms are programmed into the genetic activities of each cell at the molecular level.

The researchers focused on the circadian rhythms of the fruit fly (Drosophila melanogaster), as a model for understanding similar rhythms in the cells of other organisms.  They identified a specific gene in each cell whose activities oscillated in a 24-hour rhythm.  During the night, this gene encodes a specific kind of protein that accumulates in the cell.  It reaches a high point at the beginning of day, after which the gene shuts itself off and the protein slowly dissolves, reaching a low point at the beginning of night when the process repeats itself.  According to this year’s prize winners, the feedback loop involving this specific gene is a key part of the self-sustaining internal chronometer that shapes the functioning of all biological organisms, from flies to humans.

The committee that decides each year’s award made it clear in its statement that the work of Hall, Rosbash, and Young has important relevance for medical practice and social welfare:

“Our wellbeing is affected when there is a temporary mismatch between our external environment and this internal biological clock, for example when we travel across several time zones and experience ‘jet lag.’ There are also indications that chronic misalignment between our lifestyle and the rhythm dictated by our inner timekeeper is associated with increased risk for various diseases.”

Most commentators on the 2017 prize have highlighted this last point, about the diagnosis and treatment of illness.  Circadian rhythms influence the human body in numerous ways: via hormone levels, metabolism, temperature, and of course the sleep/wake cycle. Disruptions to the biological clock, whether through behavior (e.g., traveling across several time zones) or internal malfunctioning (e.g., a genetic mutation), can lead to a variety of serious health problems, including diabetes, obesity, cancer, cardiovascular disease, depression, bipolar disorder, memory defects, Alzheimers, and attention-deficit disorders.

The hope is that the more we learn about the elemental mechanisms of circadian rhythms, the better we can treat these problems, and prevent them from occurring in the first place.  Further research in chronobiology may show us there are better and worse times of the day for undergoing surgery, taking a medication, or participating in a psychotherapy session.

It may also give us new insights into the rhythms, cycles, and recurrent patterns in human dreaming.  Anything that gives a new understanding of sleep has the potential to provide a new understanding of dreams, since dreaming naturally emerges out of the state of sleep.  The ubiquity of dreaming in human experience throughout recorded history, in cultures all over the world, strongly suggests it is a phenomenon deeply rooted in our evolutionary heritage.  It strengthens the argument in favor of this idea to show, as this year’s Nobel winners have done, that the circadian rhythms guiding our waking and sleeping behaviors are encoded in every cell in our bodies.   There can no longer be any question that sleep is an absolutely vital feature of healthy human life.  The study of dreams can build on this solid foundation in evolutionary biology to explore in more detail what exactly is happening in the mind and body during sleep that contributes so powerfully to human health.
