I was in the pub early one evening all alone so decided to throw a few darts, when one bounced out onto the floor, as I bent down to pick it up I would swear that someone put their hand on my shoulder and I suddenly felt cold but when I straightened up there was no-one there. The pub is supposed to have a ghost but I dismissed it as probably a muscle twinge or something similar as I don't believe in such things, although I've never forgotten it.
