Hallucinations
Many of us equate them with a healthy dose of LSD. In fact, Hallucinations can happen to any of us, and can be caused by any number of things, from psychoactive drugs to bad headaches. This 350-page book from notable neurologist Oliver Sacks examines the phenomena in detail, from what they mean for our brains to how they've influenced our culture, via clinical cases, historical examples, and his own experiences.
