Quote from : Tomorrow's Eve Book

You're doubtless well aware that most of the great hypnotic patients wind up referring to themselves in the third person, like little children. They see themselves from outside their own organisms, outside their own sensory systems. In order to get further outside themselves, and help them escape their physical personality, some of them, once in the state of clairvoyance, have the curious custom of re-baptizing themselves. The dream name comes to them, no one knows whence, and by this they INSIST on being called as long as their luminous sleep endures – to the point of refusing to answer to any other name.
