Just a Thought

This is starting to sound like science fiction. Am I just making up a self-serving hypothesis as a form of self-defense? Maybe it’s just that I’ve gone crazy. I see my own mind as perfectly normal, as free of distortion. But don’t all mental patients insist that they are perfectly fine and it’s the world around them that is crazy? Aren’t I just proposing the wild hypothesis of parallel worlds as a way to justify my own madness?
