I occasionally wake up half way during the night and experience glorious intensely colorful geometric hallucinations. It definitely feels and evolves like feedback. There are sometimes beings and encounters. The colors are hyperreal, impossible to see or display on a monitor. Normal dreams don't have colors at all really. This is a natural part of our brains I guess.
