Have you ever seen something that wasn't really there? Heard someone call your name in an empty house? Sensed someone following you and turned around to find nothing?
Hallucinations don't belong wholly to the insane. Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury. In some conditions, hallucinations can lead to religious epiphanies or even the feeling of leaving one's own body. Humans have always sought such life-changing visions, and for thousands of years have used hallucinogenic compounds to achieve them.
In this book, with his usual elegance, curiosity and compassion, Dr Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us 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, a vital part of the human condition.
Oliver Sacks is a physician and the author of ten previous books, including The Man Who Mistook His Wife for a Hat, Awakenings (which inspired the Oscar-nominated film) and Musicophilia. He lives in New York City, where he is Professor of Neurology and Psychiatry at Columbia University. He is the first, and only, Columbia University Artist, and is also a Fellow of the Royal College of Physicians. In 2008, he was appointed Commander of the British Empire.
