"The Man Who Mistook His Wife for a Hat" by Oliver Sacks

This book is a classic from 1985 that every psychology student should read. The author describes ten peculiar psychological cases from his practice, including but not limited to Dr. P — the man who mistook his wife for a hat on the way from the doctor's appointment. I encourage you to read through the summaries of the cases on the Wikipedia page to kindle your interest — and then pick up the book to get the most profound details.

Overall, the cases described read almost like some messed-up science fiction. However, these were undoubtedly real (and some widely publicized)! It is insane how much of our perception is built by the unconscious mind and how humans can still operate with pieces "missing." The book is fascinating, and I highly suggest listening to it — at least to start valuing your clear mind more.
