I HATE shadow people. I used to dream about them when I was little. They would come out of the closet in the back room of the house, grab me, and try to take me to the closet. I KNEW if I reached the closet, I would be transported somewhere where I would be tortured and killed. I remember trying to scream for my parents, but no sound came out. I would usually wake up as we were going into the closet.
They had no discernable features, they were solid black, darker than darkness itself, but they were thin. And completely silent.
I thought I had finally gotten over them, then The Twilight Zone (in the '80's) had an episode called "The Shadow Man". Son of a bitch.
I haven't dreamed of them in a long time, but I'm not scared of them any more, either.
