Amos, it's not at all surprising, bcos there's plenty of cross-distribution of stories. Everyone who's seen "Close Encounters", "Fire in the Sky" or "X-Files" _knows_ what an alien looks like. "Close Encounters" was the original, which AFAIK 'standardised' reports of alien sightings. Cross-reference to the Middle Ages, when everyone _knew_ what a witch, a succubus or a ghoul looked like. Plenty of reports of those, often doing strange stuff with their victims.

Wolfgang, you sound like you're an expert (or have an interest) in the field. Is there any concensus on this kind of thing? And how does it relate to the "recovered memory" thing which there was a lot of fuss about a few years back?

Grab.
