If you haven't read the books written back in the eighties by French physicist and researcher Jacques Vallee I highly recommend all of them, about 5 in all. What many believe are "extraterrestrial" encounters are better described by what John Keel began referring to as "Ultra -terrestrial " back in the 60's. This is why so called extraterrestrial encounters are so very often mixed with what appears to be supernatural phenomena of all kinds, including Cryptid encounters. The phenomena wears many masks.
