Black-Eyed Waitress

First, I just want to say that I have never been a believer in the supernatural, paranormal, etc. I think that everything has a logical explanation that maybe only seems "bizarre" because of a certain kind of over excitement that many people have about "an experience from the other side," or what have you. There is absolutely no explanation for what I'm about to share with you, and it absolutely scares the crap out of me. Just recounting this is giving me a really creepy feeling that I don't think I'll be able to shake, maybe ever.About three years ago, I was sitting in a local coffee shop in upstate New York during a little road trip. The restaurant was empty except for me and the night waitress. She was really pleasant and talked a lot; she was offering places to check out while I was in town and seemed amazingly astute. In fact, she seemed almost prescient, even guessing my age almost to the day and month and even certain things that I was actually planning to do the next day. It was so light-hearted, I thought I really lucked out by meeting a easy-going, smart young lady quite out my my normal way.At closing time, she went to the back to, I guess, put some cash in the safe or something. As I was sitting there wondering what time I wanted to get up and hit the road again the next day, I momentarily thought I might even invite her for a few hours of "R&R." I decided instead to just remember the store and next time I passed through the area, to remember to stick my head in a say "hi" (no reason, I just wanted to play it cool and not seem overanxious at very first).So, I got up and knocked on the door in the back of the coffee shop where she went in. At this time, there were only two dim lights in the main eating area, and barely any lights in the back room where she was. I opened the door. This woman who I just finished talking to was standing facing me, JUST STANDING THERE in the back of this dark room when I opened the door. Her skin was suddenly a clammy, cracked olive color, and her eyes were just BLACK. I mean, no white at all. Her eyes and mouth was open really wide, and she was screaming in the most spine-chilling sounds, something I couldn't understand, but it definitely wasn't sounds of goodwill.I literally SCREAMED myself, and she started moving from one spot to the other through the room. Not running, just MOVING. Her clothes now looked all old, and she moved so fast; the back of the room must have been 15 feet or so back, and she just DARTED from one side of the back of the room, still facing me, to the other side, at an IMPOSSIBLE speed. Then she ran directly straight at me as I was now standing away from the door in the middle of the restaurant.I got the hell out of there, and jumped in my car still seeing her nightmarish face in the restaurant, darting it seemed to every window at this impossible velocity. The worst thing was, as I tore out of the parking lot ... I looked in my rear view mirror ... and she was SITTING IN THE BACK SEAT, still with that nightmarish expression, still screaming. Then she just vanished as I was panicking around. Just gone. I don't know what that was that spoke to me in the restaurant that day, but I know that it wasn't a prank. I swear at night sometimes I see her shadow moving in the dark in my room, just grinning a really ugly, evil grin. I haven't slept properly since.
