I was knocked unconscious twice during my youth. Both times I could see and hear what people were doing and saying, but I just could no react or do anything. They had to be in my field of view as I lay on my back, but I could not move my eyes either. This was the same both times. It's as if my subconscious took over part of the higher functions, because I was not sleeping. So I concluded that I am, at the center of the brain where the subconscious lives, but I need the rest of the brain to give me motion, memory, etc.
