There is a pattern match between UFO experiences and experiences traditionally categorized as demonic.

The finding

What the evidence shows

Some resemblance is documented: religion scholar Christopher Partridge's peer-reviewed article argues that the malevolent aliens in abduction accounts draw heavily on Christian demonology, and Pasulka points to shared reports of telepathy and voices without a moving mouth. But Pasulka herself says these parallels do not prove aliens are demons, and the reported experiences have not been independently verified. Calling the match 'beyond a doubt' overstates an interpretive comparison built on selected accounts, so the framing is one-sided. Falsifier: a systematic, controlled comparison showing that abduction and possession accounts overlap no more than they overlap with unrelated folk narratives would move this verdict toward false.
