Read” Close Encounters of the Fourth Kind” by C.D.B. Bryan. I met the author. He interviewed several contactees and he refuses to discredit them; he sort of lets several of them do that for themselves.
He decides one of three things are going on:
1) Actual abductions by aliens.
2) A widespread, well-organized hoax
3) An as yet not fully described mental illness.
