A comprehensive neurocognitive theory of dreaming based on the theories, methodologies, and findings of cognitive neuroscience and the psychological sciences.
G. William Domhoff's neurocognitive theory of dreaming is the only theory of dreaming that makes full use of the new neuroimaging findings on all forms of spontaneous thought and shows how well they explain the results of rigorous quantitative studies of dream content. Domhoff identifies five separate issues — neural substrates, cognitive processes, the psychological meaning of dream content, evolutionarily adaptive functions, and historically invented cultural uses — and then explores how they are intertwined. He also discusses the degree to which there is symbolism in dreams, the development of dreaming in children, and the relative frequency of emotions in the dreams of children and adults.
During dreaming, the neural substrates that support waking sensory input, task-oriented thinking, and movement are relatively deactivated. Domhoff presents the conditions that have to be fulfilled before dreaming can occur spontaneously. He describes the specific cognitive processes supported by the neural substrate of dreaming and then looks at dream reports of research participants. The "why" of dreaming, he says, may be the most counterintuitive outcome of empirical dream research. Though the question is usually framed in terms of adaptation, there is no positive evidence for an adaptive theory of dreaming. Research by anthropologists, historians, and comparative religion scholars, however, suggests that dreaming has psychological and cultural uses, with the most important of these found in religious ceremonies and healing practices. Finally, he offers suggestions for how future dream studies might take advantage of new technologies like smartphones.

"A comprehensive and up-to-date survey of research findings on dreams and dreaming, this book deals with important questions and provides intriguing answers."
"This is a veritable encyclopedia of the psychophysiological underpinnings of dreaming. Painstakingly researched, this exhaustive overview offers the reader unprecedented insight into one of the most perplexing and fascinating fields of study."
"G. William Domhoff is a force of nature.... One might have said of any of his last several books, this is it, this is his summa, the crowning work of his career. And then he goes on to surpass that text and write something new."
"In a tour de force, Domhoff uses contemporary research data to compare his neurocognitive theory of dreaming to its competitors, finding that claims of the latter are poorly grounded, whether they be psychoanalytic, activation-synthesis, or adaptive.... Among this book's many contributions are Domhoff's use of content analysis to explore national and gender differences in dreams, his observation of the continuity between dreaming and waking thoughts, and his masterful charting of the development of dreaming over one's life span."
"Domhoff's book is an invaluable resource that will elevate the scientific work on dreaming as well as cognitive science in general."
