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, including smart phones.

This new neurocognitive theory documents the unexpected similarities of dreaming to waking thought, demonstrates personal psychological meaning can be found in a majority of dreams reports, has a strong developmental psychology dimension, pinpoints the neural substrate for dreaming, and shows it is very unlikely that dreaming has any adaptive function.

Domhoff's neurocognitive model helps explain the neural and cognitive bases for dreaming. He discusses how dreams express conceptions and concerns, and how they are consistent over years and decades. He also shows that there may be limits to understanding the meaning of dreams as there are many aspects of dream content that cannot be related to waking cognition or personal concerns. In addition, the book includes a detailed explanation of the methods needed to test the new model as well as a case study of a comprehensive dream journal. Particularly valuable is a discussion of a new system of content analysis that can be used for highly sophisticated studies of dream content. In this provocative book, Domhoff sets forth a convincing argument that will encourage a resurgence in dream research among both new and established cognitive psychologists and neuropsychologists.

This volume describes how the conceptual and technical sophistication of contemporary cognitive and neuroscientific fields has enhanced the neurocognitive understanding of dreaming sleep. Because it is the only naturally-occurring state in which the active brain produces elaborate cognitive processes in the absence of sensory input, the study of dreaming offers a unique cognitive and neurophysiological view of the production of higher cognitive processes. The theory and research included is driven by the search for the most direct relationships linking the neurophysiological characteristics of sleepers to their concurrent cognitive experiences. The search is organized around three sets of theoretical models and the three classes of neurocognitive relationships upon which they are based. The contributions to this volume demonstrate that the field has begun to move in new directions opened up by the rapid advances in contemporary cognitive science, neuropsychology, and neurophysiology.

This book presents three lectures by Allan Hobson, entitled “The William James Lectures on Dream Consciousness”. The three lectures expose the new psychology, the new physiology and the new philosophy that derive from and support the protoconsciousness hypothesis of dreaming. They review in detail many of the studies on sleep and dreaming conducted since the days of Sigmund Freud. Following the lectures are commentaries written by scholars whose expertise covers a wide range of scientific disciplines including, but not limited to, philosophy, psychology, neurology, neuropsychology, cognitive science, biology and animal sciences. The commentaries each answer a specific question in relation to Hobson’s lectures and his premise that dreaming is an altered state of consciousness. Capitalizing on a vast amount of data, the lectures and commentaries provide undisputed evidence that sleep consists of a well-organized sequence of subtly orchestrated brain states that undoubtedly play a crucial function in the maintenance of normal brain functions. These functions include both basic homeostatic processes necessary to keep the organism alive as well as the highest cognitive functions including perception, decision making, learning and consciousness.
