Eye witness testimony is inaccurate. It can be anything from deliberate lies to just being colored by emotion or later rationalizations.... witness testimony... it's probable there are far fewer 'beings' but many interpretations and memories of them.
Your comment about films reminds me of anecdotes about the earliest motion pictures. Reportedly, audiences were afraid objects on the screen could harm them, and screamed at images of oncoming trains and pistols pointed at them. Evidence suggests we cope poorly when confronted with something new and alien to us!
