This subject has been an interest for many years of my life.
I have both family and friends whom have witnessed UFOs.
One close friend changed... psychologically, became withdrawn, anxious...she began self medicating and wouldn't say what was wrong.
Many years later, she told me she was abducted by beings that weren't like you or me...she went to bed, awoke, couldn't move as she was being 'floated' away by these strange beings.
She couldn't say anything or move her body. She passed out.
She found herself in a nearby meadow...unclothed and bleeding from a small intranasal puncture.
Nobody believed her.
You can figure out the rest.
The person I am speaking of
was a very down to Earth soul whom wasn't into making up far-fetched stories.
I believed her then...as I do to this day.
I always keep an open mind...no matter whom is speaking these days.
Concrete evidence would be in the nominal however, it NEVER fails in lacking to appear.
Is it safer to admit to lunacy?
My friend passed away some time ago...taking her story with her.
