Even Whitley Strieber raised that issue in Communion...and I wouldn't consider him religious unless he has changed.
He wrote a lot of evil/dark novels. It’s not shocking that he ended up with his experiences. He seems to have moved more toward the evil hypothesis. He has always noted that there were incidents over-blanked with evil. And maybe some evil critters. We don’t know that he has decided all the critters are evil, yet. We don’t check on him frequently. Housemate used to be a subscriber to his UNKNOWN country.
