Stayed in a hotel room at Rochester a few years back where the room I was given wasn't yet cleaned and was full of trash (this was at 5 p.m.)
I came back from the game that night and, upset that the place was so dirty, went to the office and asked to switch. I was kindly told there were no rooms left, so I asked that she come clean the room (or have someone who was around do it for her).
I should have known when she said, "Well, I do have one room..."
I took it. Got there - it was room 214, but it should have been room 213. As soon as I walked in, there was a blast of cold air. I found it odd, put my stuff down, got to work.
When undoing the bedsheets, I noticed a giant dark spot on the floor next to the bed. Scared the crap out of me, but I figured, "Eh, just a stain." It looked like Coke, so I poured some of my coke next to it. Nope, the Coke was darker. This was a bit more red.
Screw it. I'm tired. I'm going to bed. I laid down to sleep and the bed slowly started to shake - not one of those old vibrator styles, either. It went up and down, toward the headboard.
I turned on the light, grabbed my stuff, threw it all out in the hallway next to the old room six doors down, and charged into the office in my undershirt and boxers.
"You know, on second thought, I want the original room back," I said. "But you told me it hadn't been cleaned yet?" the lady told me. "No worries, it works for me."
Even though I didn't see anything that night, and hadn't believed in that stuff before then, I was scared.
I know it's a tame tale compared to others, but it certainly had me.
