Hallucinations

This book by Oliver Sacks came up once on Tim Ferriss in the episodes we index. That mention was a genuine on-air recommendation, not just a passing reference. The people who brought it up: Hamilton Morris. Every occurrence below links to the episode page and to the exact second it was said on YouTube.

Hallucinations don't belong wholly to the insane. They are commonly linked to sensory deprivation, intoxication, illness, or injury. For thousands of years, humans have used hallucinogenics to achieve them. Here, with elegance, curiosity, and compassion, Oliver Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about our brains, our culture, and ourselves.
