The Nature and Functions of Dreaming presents a comprehensive theory of dreaming based on many years of psychological and biological research by Ernest Hartmann and others. Critical to this theory is the concept of a Central Image; in this volume, Hartmann describes his repeated finding that dreams of being swept away by a tidal wave are common among people who have recently experienced a trauma of some kind - a fire, an attack, or a rape. Dreams with these Central Images are not dreams of the traumatic experience itself, but rather the Central Image reveals the emotional response to the experience. Dreams with a potent Central Image, like the tidal wave, vary in intensity along with the severity of the trauma; this pattern was shown quite powerfully in a systematic study of dreams occuring before and after the September 11 attacks in New York. Hartmann's theory comprises three fundamental elements: dreaming is simply one form of mental functioning, occurring along a continuum from focused waking thought to reverie, daydreaming, and fantasy. Second, dreaming is hyperconnective, linking material more fluidly and making connections that aren't made as readily in waking thought. Finally, the connections that are made are not random, but rather are guided by the dreamer's emotions or emotional concerns - and the more powerful the emotion, the more intense the Central Image.

Drawing on his clinical practice, his research on sleep and dreaming, and over five thousand of his own dreams, psychiatrist and psychoanalyst Ernest Hartmann proposes a new theory of dreams that shows us how they help us make sense of our emotions and, ultimately, reveal most profoundly who we are. Dreams are meaningful, he argues-and in the process takes on neurobiologists, who believe that dreams are merely random products of the chemistry of the brain, and Freudians, who attribute every dream to the fulfillment of a childhood wish. He shows how dreams, guided by the emotions of the dreamer, make broad connections among our experiences in life. In the end, he concludes, dreaming is immensely useful to the most important psychological task we face-gathering knowledge about ourselves.
