I had an unknown parasite, distantly related to Malaria, for two weeks as a child. This was just enough to push me into delirium. I "hallucinated" a black hole in my room, not one the size of my room, but real stellar proportions and gravity. I also hallucinated a radio chasing me around. I never saw, heard or felt either of them, I just knew that they were there, and were not there.
I've had wildly vivid dreams ever since. They are blandly authentic. Some of them would probably make great movies. Every night I hope I have one of those dreams, but they are becoming less and less frequent.
