I'm quacking up, weally. Maybe it's called qwuee-ativity, but here is my idea of psychosis. It walks like a duck, it quacks like a duck, so everybody assumes it's a duck. Psychosis is not a duck, however. It's something else. It is a grand illusion that dupes the audience, it is a play known only to the actor. That crazy word-salad? Not so crazy if you care to watch the play. The actor is telling you something.
