Whimsical things, like little characters and people. The way it is described it is a condition he lives with and seems to have no difficulty sorting out what's real or not. The storyline is not completely based on the hallucinations as I recall, they are a hilarious device but the Author uses to spice things up. It's like Roger Rabbit's ToonTown and the side action in Cool World. I would like to reconnect with the story because the idea of incredibly zany things happening all around intrigues me, I see the same things day after day.
