Zeo Sleep Data and the Ur-Patterns of Dream Content

So far I’ve done word search analyses on 20 series of dreams from individuals and 9 sets of dreams from large groups of people, a total of more than 18,000 dream reports. It’s too early to say anything definite about the patterns that have emerged from this data. More reports need to be gathered from a wider variety of people, and more improvements need to be made in the SDDb word search template.

Still, a few basic patterns have appeared in nearly all the collections I’ve studied. I’m calling them ur-patterns because they seem to represent deep structural elements of dream content (ur- as in “original” or “primal”). That’s my general hypothesis, anyway, and each new set of dreams is another chance to test and refine it.

Here are the ur-patterns I’ve identified so far:

  1. Of the five senses, sight words are used most often, smell and taste the least.
  2. Of the five major emotions (fear, anger, sadness, confusion, happiness), fear words are used most often.
  3. Of all the categories of cognitive activity, speech words are used most often.
  4. Of the four natural elements, water words are used most often.
  5. Falling words are used more often than flying words.
  6. There are more references to family characters than animal characters, and more to animals than to fantastic beings.
  7. There are more references to friendliness than physical aggression.

Looking at the KB DJ 2009-2010 series with Zeo sleep data (available at google docs), a scan for these patterns finds good but not perfect evidence for each one.

Vision-related words are used more frequently across all the Zeo measurements, with smell and taste words almost entirely absent. Fear words are used more frequently than other emotion words. Speech words are the most used among the cognition categories, and water is the highest among the natural elements, though earth is a consistently high second. The usage of falling words is always higher than, or equal to, flying words.

The family > animals pattern > fantastic beings was not as clear-cut. Fantastic beings always had the lowest word usage, but animals were not always lower than family. When the names of the dreamer’s immediate family were added to the search for characters, the total frequency of family-related words rose higher than the usage of animal words in 15 of the 17 subgroups.

The friendliness > physical aggression pattern was not perfectly evident either. In part this is due to a “false positive” problem in the SDDb template. The word search category for physical aggression includes the word “bit,” which the dreamer used in almost 10% of all the reports as a term meaning “small amount,” not a physical bite. I’ll provide revised numbers once I’ve fixed this. For now, looking at how often the word “bit” is used in each Zeo subgroup, it appears the physical aggression frequencies will drop below the friendliness frequencies in most, but not all, subgroups.

In sum, the ur-patterns appear across virtually all the subgroups of Zeo sleep measurement. No matter what aspect of sleep was measured, the dream reports used the same basic frequencies of words in several major categories. High or low proportions of sleep did not correlate with any major change of dream content, at least at this level of analysis.

In future posts I’ll look at the few variations from these patterns (high physical aggression, animal, flying, and earth references) in relation to the dreamer’s waking life concerns, taking the possibility of metaphorical meaning into account.

I will also look at each of the five types of Zeo data and see if I can identify any particular variations that rise to the level of statistically significant correlation. If any such correlations emerge, they may guide us toward specific areas where a measurable aspect of sleep does interact with basic patterns of dream content.

 

Jared Loughner’s Dream Journal: A “Golden Piece of Evidence”?

Jared Loughner, the alleged gunman in the shooting of Congresswoman Gabrielle Giffords, was fascinated by lucid dreaming and kept a dream journal, according to an interview with Nick Baumann in Mother Jones magazine with Loughner’s close friend Bryce Tierney: “He [Tierney] also describes Loughner as being obsessed with ‘lucid dreaming’–that is, the idea that conscious dreams are an alternative reality that a person can inhabit and control–and says Loughner became ‘more interested in this world than our reality.’  Tierney adds, “I saw his dream journal once.  That’s the golden piece of evidence,” the friend said.  “You want to know what goes on in Jared Loughner’s mind, there’s a dream journal that will tell you everything.”

Jared Loughner seems to be a mentally ill person plagued by a variety of paranoid beliefs and anxieties.  For someone so scared of shadowy, unseen powers, it makes sense that Loughner would consider his dreams (and nightmares?) to be another source of existential danger requiring extreme force to combat and control.

As someone who has devoted considerable time and energy to studying the dream journals of both healthy and mentally disturbed people, I would caution against treating Loughner’s dream journal as evidence to be used against him in a legal proceeding.  The metaphoric, multi-layered aspects of dreaming do not allow for interpretations that can be sufficiently precise for courtroom purposes. 

I would predict, however, that Loughner’s dream journal will indeed provide a “golden” opportunity to understand his concerns, conflicts, fears, and desires.  The recent paper that Bill Domhoff and I wrote in the IASD journal Dreaming on the “Van” dream series showed that a systematic statistical analysis of long-term dream content can accurately identify an individual’s personality attributes, relationships, waking activities, and cultural preferences.  (Abstract below.)  Our paper builds on lots of previous research indicating that dream content is continuous with many important aspects of a person’s waking life. 

A more speculative prediction would be that Loughner’s dreams will contain a high frequency of weapons and physical aggression.  Over the years I’ve noticed a few young men who might be described as “loners”  having elaborate dreams of using very specific weapons to fight their enemies.  As Domhoff and I found with the Van series, the influence of video games may play a role here.   I don’t know if Loughner played video games, but either way I’m guessing his dreams will reflect a familiarity with, and enthusiasm for, various kinds of weaponry.

Update 1-12-11: Today’s New York Times includes an interview with another of Loughner’s friends, Zane Gutierrez, which confirms that the alleged killer took great interest in his dreams:

“[E]very day, his friend said, Mr. Loughner would get up and write in his dream journal, recording the world he experienced in sleep and its possible meanings. ‘Jared felt nothing existed but his subconscious,’ Mr. Gutierrez said. ‘The dream world was what was real to Jared, not the day-to-day of our lives.’  And that dream world, his friend said, could be downright strange.  ‘He would ask me constantly, “Do you see that blue tree over there?” he would admit to seeing the sky as orange and the grass as blue,’ Mr. Gutierrez said. “Normal people don’t talk about that stuff.'” (p. A14)

The mention of synesthesia (the merging of sensory qualities) adds more detail to the general impression that Loughner suffers from severe mental instability.  Likewise, his solipsism (only I truly exist) indicates a possible breakdown in the ability to distinguish between waking and dreaming realities. 

Religious mystics, particularly in Hindu, Buddhist, and Daoist traditions, have frequently questioned the boundaries of waking and dreaming (e.g., Zhuangzi’s paradoxical “butterfly” dream) as a way of opening the mind to new possibilities and expanding one’s sense of compassion for all forms of life.  That does not seem to be the path Loughner followed.  The evidence so far suggests he tried to control his dreaming reality as a way of fighting off the painful, confusing pressures of waking reality.   

A warning from Plato’s Republic comes to mind: “[T]he most evil type of man is…the man who, in his waking hours, has the qualities we found in his dream state.” (IX.576.b)


Abstract for “Detecting Meaning in Dream Reports: An Extension of a Word Search Approach”:

             Building on previous investigations of waking-dreaming continuities using word search technology (Domhoff and Schneider 2008, Bulkeley 2009a, 2009b), this article demonstrates that a blind analysis of a dream series using only word search methods can accurately predict many important aspects of the individual’s waking life, including personality attributes, relationships, activities, and cultural preferences.  Results from a study of the “Van” dream series (N=192) show that blind inferences drawn from a word frequency analysis were almost entirely accurate according to the dreamer.  After presenting these findings we discuss several remaining shortcomings and suggest ways of improving the method for use by other researchers involved in the search for a more systematic understanding of meaning in dreams.

Detecting Meaning in Dream Reports: An Extension of a Word Search Approach

A new article I co-authored with Bill Domhoff is appearing in the latest issue of the APA journal Dreaming (vol. 20, no. 2, pp. 77-95).  The abstract is below.

What amazed me about this project was how easy it was to make accurate inferences about the waking life of our participant, “Van,” without ever reading his dream narratives–just by looking at the statistical frequencies with which he used certain words in reporting his dreams.

Our findings are additional evidence in favor of the idea that dreaming has meaningful psychological structure, and against the idea that dreaming is merely random nonsense from the brain during sleep.
