Hallucinations

A provocative investigation into auditory, visual, tactile and olfactory hallucinations, exploring their physiological sources and personal and cultural resonances. Many people associate hallucinations with madness, but injuries, intoxication and even just falling asleep can cause them, whether it's the geometrical shapes we see when we rub our eyes or an altered state of consciousness. Drawing on a wealth of clinical examples, historical and literary descriptions, Sacks investigates what hallucinations say about the structure and organisation of our brains, and how they have influenced folklore and art.
