Wait until you dig into the lore on capricious elves and pixies and realise that it overlaps UFO lore in the kinds of weirdness it contains, despite being recorded by people separated by centuries, continents, and cultures.
In some sense it's easily dismissed as "trivially lumping together all things we don't understand" and calling it "quantum". But on another level there does seem to be overlap: in types of experiences, places they happen, and other things I don't know about.
