from Librivox: Flying saucers are real.
Yeah. When I worked at Mescalero, they usually ignored such things, figuring they were experimental aircraft from nearby White Sands.
But the reason I started to question the "abduction" type stories is because in the early UFO books, people reported being put under a machine that made noise to examine them.
Many years later, they started reporting being put into a tube that examined them.
Any doc knows the first is an Xray machine, but the latter is a CT or MRI scanner...and one does wonder why the E.T.'s technology mirrored the changes of human radiological progress.
The Tolkien professor notes (in his "Fairie and Fantasy course) that in medieval times, people wandering in forests would see bright objects and be abducted into a timeless land, and noted the many similarities with these stories and those of modern UFO abductions.
How much is "real" and how much is our subconscious interpreting things, I do not know: Like near death experiences, there is a question if they are real or the mind's response to severe stress, since you don't have to be near death physiologically for this to occur (the book "miracle on the Hudson" shows many in that plane had such experiences).
As a Catholic christian, I have no problem: God uses our minds to talk to us, and uses natural things to encourage us, be they "coincidence" or hallucinations.
However, the problem with all of this is that humans can't always tell if the experience is real, imagination, hallucination, or even diabolic.
