Illusions

Hallucinations

Oliver Sacks

Hallucinations looks at the many ways people can see, hear, or feel things that are not actually there, from migraines and sensory loss to sleep, drugs, illness, and grief. Oliver Sacks tells the stories of patients alongside some of his own experiences, showing that hallucinations are not limited to psychosis. Readers often found the cases fascinating and accessible, though some felt the book became repetitive and wanted more explanation of the science behind them.

Phantoms in the Brain: Probing the Mysteries of the Human Mind

Sandra Blakeslee and V. S. Ramachandran

Phantoms in the Brain looks at unusual neurological cases, including phantom limbs, neglect, and people who lose a normal sense of their own body. Ramachandran uses these cases to explain how the brain builds our sense of perception and self, often through simple experiments and patient stories. Readers often described the book as fascinating and memorable, and some said it got them interested in neuropsychology. It is fairly approachable, though a few sections can be harder to follow.

The Invisible Gorilla

Christopher Chabris & Daniel Simons

The Invisible Gorilla looks at the everyday mistakes we make in attention, memory, confidence, and reasoning, and why we often trust our own minds more than we should. Chabris and Simons use experiments, stories, and real-world examples to show how easily perception and intuition can mislead us. Readers often described it as funny and thought-provoking, with examples that stick with you. It is especially useful for exploring attention and cognitive illusions.
