I have had this experience many times in the past, and it used to freek me out. I would go to sleep, then I would suddenly wake up and open my eyes. I see images of things.
I once saw a butterfly, and I followed it around the room. I mean I got up in my bed and turned my head following it until it disappeared.
I keep seeing things like that from time to time. I don't feel parallized. I can move, and follow what ever I see around.
What are these things?
