The Demon Haunted World by Carl Sagan delves into this quite a bit. It's years since I read it, but he talks about how in history people often suffered hallucinations and mass hallucinations that had a religious theme. They were visited by angels, demons, witches etc. In the 50s when Hollywood started churning out Sci-fi movies, the nature of these hallucinations altered and became all about UFOs.
