Its the Jacques Valle hyphotesis that spiriting away and alien abductions are one of the same phenomenom. Before that Jung had already written about aliens in a similar fashion, that its the scientific age interpretation of visions with new fears and symbols added in.
Its an interesting concept, there's a few ways to look at it. I like to think that if aliens do exist they might be interdimensional or something paranormal than just grey men in spaceships but i tend to see it as more psicological though. I think a lot of people are absolutely not lying about what they went through and are being genuine about seeing what they saw but it might not be a tangible phenomenom, maybe more like a mystical extasis or a dream state thats absolutely visceral. Christian mysticism is actually one of the most interesting parts of christianity, or mystics in general, some i think were legit, they may have reached something profound that can't be put into words, the contemporary take is they were just schizos or having psicotic breaks, i think that doesn't account for everything and not everyone with a story to tell is mentally ill.
