Aggression in Dreams

Hitting, fighting, chasing, shooting, killing—these are not only common themes in the news each day, they are also recurrent features of our dreams at night. Few studies have focused specifically on aggression in dreaming, even though Sigmund Freud, the founder of psychoanalysis, claimed that “the inclination to aggression is an original, self-subsisting instinctual disposition in man” (Civilization and its Discontents, 1930). A combination of old and new methods of research can shed light on how this primal instinct plays out in our dreams.

Who Has Aggressive Dreams?

The Hall and Van de Castle system (1966) of dream content analysis has codes for three kinds of social interactions: friendly, sexual, and aggressive. Research using the HVDC system has suggested a few basic patterns in the frequency of aggression in dreams:

  • Men have more aggression, especially physical aggression, in their dreams than do women.
  • Women are more likely to be victims than initiators of aggression in dreams.
  • Children have more aggression in dreams than do adults, especially involving attacks by animals.
  • Older people have less aggression in dreams than do younger people.

Hundreds of studies have used the HVDC method over the past several decades, and their findings support the basic idea that aggression is an innate feature of human dreaming.

Why Do We Have Aggressive Dreams?

An additional perspective comes from using word search technologies to identify significant patterns of meaning in dream content. The Sleep and Dream Database (SDDb) has a template with a category for physical aggression, and a large collection of dreams to study for a specific theme like this.

The SDDb Baseline dreams are a good place to start—a set of 5,321 dreams (3,227 females, 2,094 males) that represent a composite portrait of dreaming in general (the reports were given in response to a question about “your most recent dream”). Although limited in many ways, the Baseline dreams offer an empirical basis for making comparisons across different sets of dreams. This can help in identifying trends and patterns that would be difficult to see otherwise.

Applying the word search category for physical aggression to the female Baselines, we find that 15.1% of the dreams include at least one word relating to physical aggression. Applying the same word search category to the male Baselines yields a result of 21.5% of the dreams with at least one reference to physical aggression. (The combined Baselines figure is 17.6%.) So this analysis confirms the finding of the HVDC system that men’s dreams, on average, seem to involve more physical aggression than do women’s dreams. The top ten words used in these dreams were the following: Hit, kill, fight, chasing, killed, shot, fighting, chased, war, shooting.

Turning to the dreams of individuals who have kept track of their dreams for a lengthy period of time, a great deal of variation appears in the frequency of physical aggression. For example, “Tanya,” a young woman, has a relatively high proportion of physical aggression in her dreams (25.4%, in 563 reports), about the same as “Lawrence,” an older man (25.7%, in 206 reports. Another young woman, “Jasmine,” has low physical aggression in her dreams (10.5%, in 800 reports), just like “RB,” an older man (11.8%, in 51 reports).

There is clear evidence that experiences with physical aggression in waking life can increase the frequency of its appearance in dreaming. The best examples are “Mike,” who served as a medic during the Vietnam War and whose collection of dreams includes a very high proportion of physical aggression (76.3%, in 97 reports). In the four sets of dreams from “Beverley” from 1986, 1996, 2006, and 2016, the first set has much more physical aggression (11.9%, in 253 reports) than in the other three (5.7%, in 687 reports), which accurately reflected her involvement in that earlier time period with a violent religious cult.

To help shed light on the role of culture in dreams of physical aggression, the SDDb also includes sets of dreams from non-Western people, which can be analyzed in the same way. For the Mehinaku people of the Amazonian rain forest, a collection of 383 dreams had 22.5% with at least one reference to physical aggression. For a group of Nepalese college students, their dreams (535) had 18.1% with a reference to physical aggression. Three groups of African church members reported dreams (142) with a 19% frequency of physical aggressions. These findings are close enough to the SDDb baselines overall figure of 17.6% to suggest that culture is not a decisive factor in this aspect of dream content.

Concluding Insights

Aggression appears to be a normal feature of human dream content, across different cultures.

Men seem to have more physical aggression in their dreams, although some women have high levels, too.

Dreams of physical aggression can accurately reflect actual aggressions in waking life, so an unusually high level of dream aggression, or a sudden change in dreams to a higher level of aggression, might be a therapeutically valuable sign.

Many dreams of physical aggression do not, however, reflect actual experiences of aggression. These dreams may use violence as a metaphor (e.g., a dream of physical attack as a metaphor of feeling emotionally vulnerable). They may reflect instances of fictional aggression (e.g., seen in a movie). They may be anticipations of violence that may happen at some point in the future (e.g. a threat simulation).

Aggression in dreaming can be viewed as an internal form of play-fighting—the most common form of play in the animal kingdom, and very frequent among humans, too. Play-fighting functions as a way of preparing for future challenges, and also for diminishing and defusing emotional tensions that can lead to actual violence. The same psychological dynamics of play-fighting seem to be operative in dreaming, too.

More Dream Recall During the Covid-19 Pandemic

A new survey shows a rise in dream recall, especially among younger people.  In the past month, about 30% of the American adult population has experienced an increased frequency of dream recall. Twice as many younger people (ages 18-34) as older people (55+) are remembering more dreams than usual.

Those are among the initial findings from a new survey I commissioned from YouGov, to get a quick snapshot of how people’s dreams have responded to the Covid-19 outbreak. Field work for the online survey was conducted April 1-3, 2020, with 2,477 American adults. The results have been weighted to approximate the US adult population.

Overall, 11% of the respondents to this survey said their dream recall had “increased a lot,” and 18% said it had “increased somewhat.” Only 4% said their dream recall had “decreased a lot,” and 3% “decreased somewhat.” A majority of people, 65%, reported no change in their dream recall.

The people whose dream recall has been most impacted are younger people, ages 18-34. Their recall increased a lot (18%) or somewhat (22%), compared to the older group of 55+ whose recall increased a lot (5%) or somewhat (14%). People ages 35-54 were in the middle, with 10% increased a lot and 18% increased somewhat.

With the help of research psychologist Michael Schredl, an additional analysis of the raw, unweighted responses showed that, when age is factored in, there are no additional correlations between increased dream recall frequency and the demographic variables of gender, ethnicity, education, or presidential approval.

It is worth noting that younger people also reported less dream recall than other age groups, with 7% of people 18-34 saying their dream recall had decreased a lot, and 5% decreased somewhat. The corresponding figures for people 35-54 are 3% and 3%, and for 55+, 2% and 2%.

Further analysis will hopefully reveal deeper patterns in these data, but for now it seems clear that the Covid-19 outbreak has impacted the dream lives of younger people much more strongly than older people. At least three possible explanations for this difference come to mind.

First, many previous studies have shown that young people in general have higher dream recall compared to older people. Perhaps it makes sense that during a time of collective crisis, younger people’s dreams would be more sensitive to change and disruption, since they are already remembering more dreams to begin with.

Second, the economic and social disruptions of the past month may have taken an especially hard toll on younger people, who tend to have fewer financial resources and depend more on urban social activities than older people. Younger people right now may be more exposed to the severe uncertainties and dislocations of the pandemic, generating a host of negative emotions that would likely spill into their sleep and dream lives. Stress, anxiety, and trauma are well-known triggers for poor sleep and unsettled dreaming.

Third, dreams do not simply reflect our present difficulties; they also imagine new possibilities and alternative paths into the future. This is the visionary, creative problem-solving aspect of dreaming. Perhaps younger people, with their naturally high dream recall and longer time horizons, have been stimulated by this crisis to even more dreaming than usual, precisely because of the urgent need for deeper wisdom and visionary guidance to lead us forward.

A final thought: The survey did not include participants younger than 18, but given the trend line among the three age groups, these findings raise the distinct possibility that children and teenagers up to the age of 17 are experiencing the most disrupted dreaming of all. Future research will have to verify that inference, but it might be worthwhile for parents, teachers, and therapists to consider the pandemic’s distinctive impact on children, not just in their waking lives but in their sleep and dreaming, too.

Next, I will post initial results from studying a collection of pandemic-related dream narratives, including several from January and February that anticipated significant developments in the crisis.

Attitudes Towards Dreaming: New Research

A new study explores the demographic variables that correlate with positive vs. negative attitudes towards dreams.

In the latest issue of the International Journal of Dream Research, Michael Schredl and I published the results of a new study on people’s attitudes towards dreaming. Several studies have been done previously looking at differences in people who have a positive view towards dreams versus people who have a negative view towards dreams. Most studies have found that younger people have more positive attitudes towards dreams than older people; women have more positive attitudes than men; and people with high dream recall have more positive attitudes than people with low dream recall.

Our study replicated those findings, and went beyond them by looking at three additional variables: ethnicity, education, and religion. The results shed new light on the sociology of dreaming in the contemporary United States.

The study involved an online survey of 5,255 American adults, administered by YouGov, a professional opinion research company. In addition to their demographic background, the participants were asked several questions about their attitudes towards dreams. These questions took the form of six statements about dreams, presented in random order. The participants were asked if they agreed or disagreed with each statement:

  • Some dreams are caused by powers outside the human mind.
  • Dreams are a good way of learning about my true feelings.
  • Dreams can anticipate things that happen in the future.
  • Dream are random nonsense from the brain.
  • I am too busy in waking life to pay attention to my dreams.
  • I get bored listening to other people talk about their dreams.

The first three of these statements were considered positive, in that they regard dreaming as something real, powerful, and valuable. The second three statements were considered negative in dismissing dreams as unreal or insignificant.

Our analysis of the results led to several new and interesting findings. In terms of ethnicity, the blacks in this sample had significantly higher frequencies of agreement with the positive statements about dreams, and lower frequencies of agreement with the negative statements, compared to whites. Hispanics had more agreement with the positive statements than the whites, but not as much as the black participants. At the same time, Hispanics agreed more with the negative statements than either the blacks or whites.

In terms of education, we analyzed the participants in two groups: those who had attended at least some college, and those with at most a high school degree. The differences were fairly small between these two groups. The people with more education were somewhat more likely to agree with the “bored by other people’s dreams” statement. The people with less education were somewhat more likely to agree with the “powers outside the human mind” and “anticipating the future” statements.

The most intriguing results came from the religion question. We found that religious orientation correlates strongly with attitudes towards dreaming. Atheists and agnostics were mostly likely to disagree with the positive statements and agree with the “random nonsense” statement. The Protestants and especially the Catholics were more likely to agree with the “powers outside the human mind” and “anticipating the future” statements. The participants who identified themselves religiously as “something else” had the least negative and most positive attitudes towards dreaming of all the groups. This seems like an especially important avenue for future research, looking more carefully at the “something else” population to study how their unconventional religious outlook affects their attitudes towards dreams. Our findings suggest that dreaming is an especially important part of these people’s spiritual lives.

This study provides new clarity about the demographic qualities that are most often associated with positive or negative attitudes towards dreams. The people in contemporary American society who are most intensely engaged with dreaming (“hyper-dreamers”) tend to be young, female, non-white, slightly less educated, and more spiritual than religious. The people who are least engaged with and most dismissive of dreams (“hypo-dreamers”) tend to be older, male, white, slightly more educated, and atheist or agnostic. These are broad tendencies with lots of individual variation, but they do suggest a deeper connection between certain clusters of demographic qualities and how people relate to their dreams in the present-day United States.

Sexual Dreaming Before Sexual Activity

imagesSexual dreams have long been part of human experience, as we know from historical sources.  For example, the Oneirocritica of Artemidorus, an ancient manual of dream interpretation, devoted several pages to the various types and classes of sexual dreams.

 

However, we do not know how widespread sexual dreams are, who has them most often, and when they begin.

 

In a survey I commissioned a couple of years ago, nearly 3000 American adults were asked the question, “Have you ever had a dream with sexual feelings or experiences?”  Of those who answered “Yes,” a follow-up question was asked: “Did you have any sexual dreams before your first sexual activity in waking life?”

The answers to the first question were 69% Yes and 24% No for the men (1912 of them), and 58% Yes and 34% No for the women (1058 total), with 7% of the men and 8% of the women responding “Not Sure.”

On most other typical dreams questions (e.g., chasing, falling, visitation) the women answered Yes more often than did the men.  Sexual dreams stood out as a significantly more frequent experience for the men.

For the follow-up question about sexual dreams before sexual activity, the gender disparity was even bigger: 48% of the men said Yes and 22% said No, whereas only 23% of the women said Yes while 39% said No.

Looking more closely at follow-up question results, the age of the participants mattered a lot.  The frequency of Yes answers was much higher for younger than older people, although the gap between males and females remained for all ages.

 

  Males     Females    
Age Yes No N/S Yes No N/S
18-29 76% 8% 15% 55% 22% 22%
30-49 55% 16% 29% 31% 37% 32%
50-64 44% 24% 33% 17% 39% 44%
65+ 37% 30% 33% 11% 48% 42%

 

Other demographic variables (e.g., race, income, education, religion) did not correlate with any significant differences.

What can we learn from these results?

First, we have to consider the limitations of the data. Many people are simply reluctant to talk about sex.  Dreams sometimes portray taboo, socially frowned upon sexual behaviors that people may not want to admit.  Some religious traditions teach that sexual dreams should be shunned as demonic temptations.  More generally, people vary in how well they can recall different types of dreams from earlier in life.

All these factors suggest the survey results are underestimating rather than overestimating the frequency of sexual dreams. Some of the participants probably answered “No” when the actual truth was “Yes,” while it’s unlikely that many participants said “Yes” when the accurate answer would have been “No.”

To explain these findings, we can appeal to both biology and culture.  It makes sense that young people entering their prime years of reproductive potential would have dreams that anticipate and prepare them for this fundamental biological goal.  Just as some nightmares simulate threats to our survival (e.g., being chased by wild animals) so we’re better prepared to face them in waking life, it could be that sexual dreams are simulating reproductive opportunities we will hopefully have in the future.  Such dreams might have less biological value or significance for older people.

It could also be that young people in contemporary America are more likely to dream about sex because they are immersed in a culture filled with sexually arousing content.  Dream content accurately reflects people’s biggest emotional concerns, and it’s plausible to assume that many young people today are thinking a lot about sex before they are sexually active.   Again, such dreams would be less likely among older people whose emotional concerns no longer center on sexuality.

Both biological and cultural factors could also account for the gender differences.  The process of sexual maturation may generate stronger physical pressures for young males than females, prompting a higher proportion of sexually explicit dreams.  Cultural portrayals of sexuality certainly seem to emphasize male rather than female perspectives, which may stimulate relatively more dreaming about this subject.

These explanations are admittedly speculative and open to question.  However, it is clear that dreaming is closely connected to our nature as sexual beings.  Even before sexual activity in waking life we tend to be sexually active in our dreams, anticipating how it will happen, what it will feel like, and with whom we’ll share the experience.  The fact that some dreams can lead to actual climax for both men and women suggests that dreaming is, at one level, a physiologically hard-wired means of preparing us for our lives as reproductive beings.

We Have a Winner!

Congratulations to Michael Paul Coder, the winner of the dream research contest I posed last week.  Michael correctly identified the gender, age, and dream type of six sets of dreams using only word search frequencies and my baseline hypotheses to make his inferences.  He also correctly identified the bonus questions of which sets of dreams came from the same person.  Best of all from my point of view, Michael showed me his work so I could see how he applied the baseline hypotheses to the word search frequencies.  The correct answers are below.

 

Perhaps it should not be surprising to learn that Michael is a talented and experienced software architect with a website, Lucid-Code, offering a variety of technologies for exploring consciousness in dreaming.

 

His success is encouraging because it shows that an essentially automatic process of word frequency analysis can reveal meaningful patterns in dreaming. It should give us additional confidence that this kind of approach to dream research can provide quick, accurate, and reliable results.

 

What other aspects of dream meaning can be illuminated by this method?  That’s an open question….

 

Set 1: Female, younger than 18, MRDs.

Set 2: Male, older than 18, MRDs.

Set 3: Male, older than 18, MRDs.

Set 4: Male, older than 18, MRDs.

Set 5: Female, younger than 18, MRDs.

Set 6: Male, older than 18, MRDs.

Bonus question: Sets 1 and 5 come from the same person, and Sets 3 and 4 come from the same person.
