The main character at first seems sane, with slight delusions of grandeur. However, these grow to obscure reality, while meanwhile he begins to decide things have happened or will happen with no evidence or reason to think so at all. Finally, his declarations lose meaning altogether. Far from being false, they are no longer even understandable. He is incapable of recognizing his true position or responding appropriately. He is very traditionally mad, in that he does not understand the world around him, and in fact thinking his is someone and somewhere else. Thus, he is mostly harmless, despite his incomprehensibility and general strangeness.
