Suggestions from the group: Bob Dylan (Chronicles), Ramachandran (New Yorker article, others?), Oliver Sacks (Uncle Tungsten: Memories of a Chemical Boyhood), Joseph Heller (Catch-22)
I'd like to add: Donna Williams - she has a series of autobiographies about her experiences living with autism, including vivid descriptions of her inner world. Titles include: Nobody Nowhere, Somebody Somewhere, Like Color to the Blind, and Everday Heaven.
