I thought they didn't exist also..But I seen 2 of them.
I was driving one night and I seen a hitch hiker. It was a blonde girl about early 20's. I pulled over and looked back and she was gone. There wasn't anything around for her to hide behind .
I was at a restaurant. A real old one about 100 years old .I went to use the can and there was some dude just standing by the garbage can wiping his hands with a paper towel. I went to the urinal to take a piss and noticed the dude just disappeared.
I wasn't under the influence of any drugs or booze. and I'm sane most of the time
