A conscious mind in a sleeping brain: the title of this book provides a vivid image of the phenomenon of lucid dreaming, in which dreamers are consciously aware that they are dreaming while they seem to be soundly asleep. Lucid dreamers could be said to be awake to their inner worlds while they are asleep to the external world. Of the many questions that this singular phenomenon may raise, two are foremost: What is consciousness? And what is sleep? Although we cannot pro vide complete answers to either question here, we can at least explain the sense in which we are using the two terms. We say lucid dreamers are conscious because their subjective reports and behavior indicate that they are explicitly aware of the fact that they are asleep and dreaming; in other words, they are reflectively conscious of themselves. We say lucid dreamers are asleep primarily because they are not in sensory contact with the external world, and also because research shows physiological signs of what is conventionally considered REM sleep. The evidence presented in this book-preliminary as it is-still ought to make it clear that lucid dreaming is an experiential and physiological reality. Whether we should consider it a paradoxical form of sleep or a paradoxical form of waking or something else entirely, it seems too early to tell.

What, if anything, do dreams tell us about ourselves? What is the relationship between types of sleep and types of dreams? Does dreaming serve any purpose? Or are dreams simply meaningless mental noise--"unmusical fingers wandering over the piano keys"? With expertise in philosophy, psychology, and neuroscience, Owen Flanagan is uniquely qualified to answer these questions. And in Dreaming Souls he provides both an accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature and function of dreaming. Flanagan argues that while sleep has a clear biological function and adaptive value, dreams are merely side effects, "free riders," irrelevant from an evolutionary point of view. But dreams are hardly unimportant. Indeed, Flanagan argues that dreams are self-expressive, the result of our need to find or to create meaning, even when we're sleeping. Rejecting Freud's theory of manifest and latent content--of repressed wishes appearing in disguised form--Flanagan shows how brainstem activity during sleep generates a jumbled profusion of memories, images, thoughts, emotions, and desires, which the cerebral cortex then attempts to shape into a more or less coherent story. Such dream-narratives range from the relatively mundane worries of non REM sleep to the fantastic confabulations of deep REM that resemble psychotic episodes in their strangeness. But however bizarre these narratives may be, they can shed light on our mental life, our well being, and our sense of self. Written with clarity, lively wit, and remarkable insight, Dreaming Souls offers a fascinating new way of apprehending one of the oldest mysteries of mental life.

An introduction to the psychology, philosophy, and neuroscience of consciousness, including sleep, dreaming, meditative, and altered states.

"Sleep is one of the most important but least understood aspects of our life, wellness, and longevity ... An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives. Now ... neuroscientist and sleep expert Matthew Walker gives us a new understanding of the vital importance of sleep and dreaming"--Amazon.com.

A renowned philosopher of the mind, also known for his groundbreaking work on Buddhism and cognitive science, Evan Thompson combines the latest neuroscience research on sleep, dreaming, and meditation with Indian and Western philosophy of mind, casting new light on the self and its relation to the brain. Thompson shows how the self is a changing process, not a static thing. When we are awake we identify with our body, but if we let our mind wander or daydream, we project a mentally imagined self into the remembered past or anticipated future. As we fall asleep, the impression of being a bounded self distinct from the world dissolves, but the self reappears in the dream state. If we have a lucid dream, we no longer identify only with the self within the dream. Our sense of self now includes our dreaming self, the "I" as dreamer. Finally, as we meditate—either in the waking state or in a lucid dream—we can observe whatever images or thoughts arise and how we tend to identify with them as "me." We can also experience sheer awareness itself, distinct from the changing contents that make up our image of the self. Contemplative traditions say that we can learn to let go of the self, so that when we die we can witness its dissolution with equanimity. Thompson weaves together neuroscience, philosophy, and personal narrative to depict these transformations, adding uncommon depth to life's profound questions. Contemplative experience comes to illuminate scientific findings, and scientific evidence enriches the vast knowledge acquired by contemplatives.

An introduction to the art of lucid dreaming discusses the techniques of becoming a conscious participant in one's dreams, the mechanics of sleep, and dream analysis and interpretation

A world at once familiar and unimaginably strange exists all around us, and within us – it is the vast realm of consciousness. In The Head Trip, science journalist Jeff Warren explores twelve distinct, natural states of consciousness available to us in a twenty-four-hour day, each state offering its own kind of knowledge and insight – its own adventure. The hypnagogic state, when our minds hover between waking and sleeping, can be a rich source of creativity and even compassion. Then there’s the Watch, an almost magical waking experience in the middle of the night that has been all but lost to electric light and modern sleep patterns. Daydreaming and trance, lucid dreaming, the Zone, and the Pure Conscious Event – from sleep laboratory to remote northern cabin, neurofeedback clinic to Buddhist retreat, Warren visits them all. Along the way, he talks to neuroscientists, chronobiologists, anthropologists, monks, and many others who illuminate his stories with cutting-edge science and age-old wisdom. On this trip, all are welcome and no drugs are required: all you need to pack are a functioning cerebrum and an open mind. Replete with stylish graphics and brightened by comic panels conceived and drawn by the author, The Head Trip is an instant classic, a brilliant and original description of the shifting experience of consciousness that’s also a practical guide to enhancing creativity and mental health. This book does not just inform and entertain – it shows how every one of us can expand upon the ways we experience being alive.
