Under hypnotic regression they recalled being captured by non-human entities in a flying saucer, given medical examinations and released.
My investigation into this involved accessing Barney Hill’s memory of the event. Not only did Barney believe he had been abducted, but the memory was attached to an actual physical event. I’m not going to say where “flying saucer” originated or who the occupants were. But upon my initial probe I can say with certainty that this event was not a product of their imagination or any hallucination.
More to come upon further investigation.
