From the bestselling author  of Musicophilia and The Man Who Mistook His Wife for a Hat, a  provocative investigation into hallucinations – auditory, visual, tactile,  olfactory – their many guises, their physiological sources, and their  personal and cultural resonances.

Hallucinations, for most people, imply madness. But there are many  different types of non-psychotic hallucination caused by various illnesses or  injuries, by intoxication – even, for many people, by falling sleep. From the  elementary geometrical shapes that we see when we rub our eyes to the complex  swirls and blind spots and zigzags of a visual migraine, hallucination takes  many forms. At a higher level, hallucinations associated with the altered  states of consciousness that may come with sensory deprivation or certain  brain disorders can lead to religious epiphanies or conversions. Drawing on a  wealth of clinical examples from his own patients as well as historical and  literary descriptions, Oliver Sacks investigates the fundamental differences  and similarities of these many sorts of hallucinations, what they say about  the organization and structure of our brains, how they have influenced every  culture’s folklore and art, and why the potential for hallucination is  present in us all.
