A Festival of Dreams

Several hundred people from all over the world gathered in Scottsdale, Arizona this week to discuss the latest findings and methods in dream research.  The 35th annual conference of the International Association for the Study of Dreams  featured five days of panels, workshops, and artistic events.  A lively mix of academic symposium, spiritual retreat, and collective self-experiment, the IASD conference offers a stimulating variety of approaches to the nature and meaning of dreams.

Here are several highlights from the sessions I attended.

Remington Mallet, a doctoral student in cognitive neuroscience at the University of Texas, Austin, described exciting new research on “the ability to communicate in real-time between sleeping and waking.”  This theme has been explored in fictional form in various movies and television shows, from “Inception” and “The Matrix” to “Dream Corp. LLC.” Mallet analyzed the sleeping-waking communications portrayed in these popular media in relation to current scientific knowledge about what is and isn’t possible.  Mallet concluded that the media portrayals are far ahead of the actual science, but new technologies are moving quickly in the very same directions envisioned by the movies and television shows.

Sharon Pastore and Tzivia Gover of the Institute for Dream Studies gave a moving presentation on the common themes in the dreams of those who care for people with Alzheimer’s and other forms of dementia.  Building on research on dreams and bereavement, they described how simple methods of exploring dreams can be helpful for the caregivers, whether professionals, friends, or family members: “Dreamwork can guide decisions in the care and communication with loved ones, as well as coping/healing.”  In additional to academic research, Pastore and Gover drew on personal experiences of caring for a parent with dementia to illuminate the value of dreams for the caregiving process.

Robert Stickgold, an associate professor of psychiatry at Harvard Medical School, gave a fascinating keynote address on the role of sleep and dreaming in memory formation.  This has been a controversial topic in the field, with some researchers questioning the connection between sleep, dreams, and memory.  Stickgold granted that dreams rarely include episodic memories (i.e., direct, unmodified re-playings of a waking event).  But he laid out extensive evidence to support the idea that different stages of the sleep cycle are important for memory stabilization.  Sleep seems to help people better remember the emotionally relevant aspects of a waking experience.  He didn’t talk a lot about dreams, but he did note some studies “demonstrating the explicit incorporation of waking learning experiences into dream content… [S]uch incorporation is accompanied by enhanced sleep-dependent consolidation of the learning task.”  In other words, the more people dreamed about the learning task, the better they remembered it the next day.  The best part of Stickgold’s address, from my perspective, was his willingness to admit he does not have an easy answer to the “hard question” of how to relate the psychological experience of dreaming with the neurophysiological processes of sleep.  It was a refreshing statement of epistemological humility, and quite a contrast to the views of his predecessor at the Harvard lab, J. Allan Hobson, who had no doubt about the right answer to the hard question.

Linda Mastrangelo, a psychotherapist with a private practice in the San Francisco Bay Area, explored in detail a series of her own dreams in which she found unexpected connections with her family heritage, ancestral roots, and places of origin.  She combined psychology, myth, art, and sacred geography to trace out a map of her dreaming landscapes.  The frequency of certain places in her dreams inspired her to learn more about her own spiritual grounding in special features of the land, and to deepen her awareness of the wisdom traditions and ecological teachings that have grown around these places over the ages.  As Mastrangelo made clear, this is a process that anyone can pursue in exploring their own symbolic connections between dreaming and place.

Mark Blagrove, a professor of psychology and director of the sleep laboratory at Swansea University in the UK, proposed a theory of dream function that centered on the evolutionary value of empathy.  Drawing on the studies of Raymond Mar and Keith Oatley about fiction and empathy, Blagrove presented evidence in favor of a theory that telling dreams has the effect of eliciting greater empathy towards the dreamer, which strengthens interpersonal bonding and thus enhances reproductive fitness.  Blagrove made thought-provoking use of Mar and Oatley’s psychological analyses of fictional literature as a powerful means of simulating social experience and boosting our capacity to understand other people who are different from ourselves—that is, boosting our capacity for empathy.  After exploring the connections between empathy and dream-telling, Blagrove passed the microphone to Katja Valli, an assistant professor of cognitive neuroscience at the University of Skvode, Sweden, who agreed beforehand to offer constructive comments on the proposed theory.  This was an admirable exercise in scholarly dialogue, and a valuable opportunity for everyone in the audience to observe the kind of critical scrutiny that can help improve our ideas and sharpen our awareness.

Next year’s IASD conference will be held June 21-25 in the Netherlands, at the Rolduc Abbey conference facility in Kerkrade, about 200 kilometers south of Amsterdam.  The Abbey is a glorious 12th century structure where the IASD has hosted two previous conferences.  I can’t wait!

Proud to Be a Primate

“Our goodness is as deep as our darkness”—that was Kimberley Patton’s gloss on the findings of Franz de Waal, a primatologist who spoke on Saturday at the American Academy of Religion conference in Atlanta.  De Waal’s new book, Age of Empathy (2010), shows that cooperation, reciprocity, and conflict-resolution are just as natural in primates as are aggression and competition.  Contrary to the Social Darwinist assumption that nature is bloody “red in tooth and claw,” de Waal’s research proves that non-human animals have all the basic building blocks of morality.  This means that human morality is not just a matter of controlling our violent, selfish instincts, but rather enhancing and refining our other instincts for empathy, compassion, and sociability.

 Also commenting on de Waal’s research was Armin Geertz, who highlighted the core idea of evolutionary biology that “all life is continuous.”  What seems unique about humans is actually an extension of abilities and behaviors we find in other animals.  Looking ahead to the future of primate research, de Waal said, “the trend is toward the continuity of humans and animals.”

 Is this true of religion? When elephants mourn their dead, chimpanzees dance in rainstorms, and wolves howl at the moon, are we seeing the building blocks of spirituality? Can animals have mystical experiences?   De Waal said it was difficult as a biologist to address such questions, but he did not rule out the possibility of affirmative answers. 

 Score a point for scientific open-mindedness.  

 What about dreaming? Both Patton and Geertz, professors of religious studies, mentioned dreaming as a universal human experience that factors into all religious traditions.  De Waal did not talk about dreams directly, but the cognitive abilities he has identified in non-human primates (empathy, imagination, pretend play, etc.), combined with the similarities in brain functioning across all primate species, strongly suggest that humans are not the only dreamers in nature.

 In his earlier book Chimpanzee Politics (1998) de Waal talked about the dreams of people who study primates:

 “That chimpanzees are experienced in the first place as personalities is evident from the dreams of those of us who work with them.  We dream about these apes as individuals, in the same way that other people dream about their fellow human beings as individuals.  If a student were to say that he or she had dreamed of an ape I would be no less surprised than if someone claimed to have dreamed of a human.

 “I clearly remember the first dream I had about the chimpanzees.  In it my preoccupation with the distance between them and me was apparent.  During this dream the large door to their quarters was opened for me from the inside.  The apes were pushing each other aside in order to get a good look at me.  Yeroen, the oldest male, stepped forward and shook my hand.  Rather impatiently he listened to my request to come in.  He refused point blank.  That was out of the question, he said, and besides, their society would not suit me: it was much too harsh for a human being.” (41)
