Some say that if you stay up late night, you will have sudden figures popping out of nowhere resembling the things you do. Perhaps the brain was tired and couldn't really project a much active system and thus you started to "hallucinate." The occipital lobe, the back part of the brain, probably was tired like the rest of the parts of the brain. Now, I do not know if staying up late could effect the way of thinking but I am sure that staying up late can effect the occipital lobe, it's not lethal, just need some sleep if you are staying up late. And probably you need to rest your eyes, too.
