Talk about BS.
The vast research of John Mack, psychiatrist/prof of Harvard Medical, dismissed that as ridiculous. Most people who have been abducted lurked in the shadows and wouldn't have come out were it not for extreme trauma.
And BTW nearly all are still in the shadows.
So much for attention.
John Mack sells books as a priority.
“The question of physical evidence”
“Finally-and important for me to underscore as a clinician-in speaking to the experiencers in a manner that accepts the emotional truthfulness of their reports, I am not taking a position that validates the literal occurrence of these experiences in our physical reality; good clinical practice, especially in cases of traumatized individuals, must follow different guidelines than “objective” scientific investigation.” ~ John Mack M.D.
