This is a scanned brief chapter from Dr. Oliver Sacks's latest book, Hallucinations. Dr. Sacks is one of our neurology "heroes;" a discerning mind of many disciplines, a wonderful heart for people, and the ability to weave these together in the form of a great writer.
I believe everyone should read his book, to know more about ourselves, Humanity. But this chapter in particular is relevant to my patients with narcolepsy, and is a wonderful and quick read.
I apologize in advance for my poor copy skills. Hopefully the excellent chapter makes up for it.
