Just to add to the creepy stories ... One that didn't happen in MY house (too many of those to go into) was when I was staying overnight at a friend's house - downstairs on the sofa bed. In the early hours, I woke up to hear a noise in the kitchen. Thinking that one of the kids had got up to make himself a snack (and hoping for the same) I went to the kitchen. The light was off, but her son's football was gently rolling from one side of the room to the other, again and again, then it would stop, then it would start again ... I ran upstairs and knocked at my friend's bedroom door, apologised, and explained what had happened. "Oh that's just Eric" she explained, and settled me down on a campbed in her daughter's room. In the morning, she explained that Eric had been the caretaker at a sports club at the back of the houses (which had been built over the field where he used to play football). She said that he often visited a couple of the houses where the children had footballs. BTW she was a chemist, science to the core, not religious, but she was prepared to just accept it and not worry about Eric's nocturnal visits !
