Hallucinations. Oliver Sacks

Hallucinations have always occupied an important place in human culture and mental life, and — no matter how grotesque it sounds — directly influenced our perception of reality. Could the geometric patterns that flash before our eyes during migraines be the source of primitive art? How are Lilliputian hallucinations related to images of elves, leprechauns and fairies? How did nightmares, when we are suffocated by an unknown sinister entity, shape people's ideas about demons, witches or aggressive aliens?

We are used to considering hallucinations a sign of madness or illness. But in fact, all people have the ability to do so — it is built into the very architecture of the nervous system. Based on his own experience, numerous clinical cases and famous historical examples, legendary neurologist Oliver Sacks reveals the secret of these sensory deceptions: what they tell us about the brain, how they shape our worldview and influence the history of mankind. Step by step, the author debunks stereotypes surrounding the topic of hallucinations through first-hand accounts from people who have experienced them. After all, only by looking your fears in the eye can you understand and overcome them.
