Oliver Sacks

Oliver Sacks is a neurologist and author of some of my favorite books. This is an article about one of his books, "Hallucinations", where he describes how people can hallucinate through any and all of the 5 senses. He says, "The brain has to keep active, it has to keep going and if it's not being fed through the senses, the eyes and ears and nose, it will dip into the brain and come up with something." I kind of wish this happened to me more often.
