"There is something fundamentally different about mental images drawn from memory--when you picture yourself or a friend or a celebrity, say--and your self-image. The brain seems to build a self-model, a representation of your own body within your mind, so robust that you may glimpse or even confront your own 'avatar' in certain fringe states of consciousness--dreams, memories, and fantasies wehre you watch yourself in third person--and through the course of 'glitches' in conscious experience, such as out-of-body experiences (OBEs) or autoscopy, the spooky phenomenon of seeing your own double."
