Of course, there's the classic Dickens' "A Christmas Carol", with the 4 spirits (yes, 4...don't forget ol' Jacob Marley!). But what about real hauntings related to Christmas? The nearest I can think of was a sad story that happened about 5 years ago, in a small town not far from where I live. About a week before Christmas, there was a terrible housefire in a rural neighborhood, and the mother and her 4 children died. The father escaped; he said he'd left the house right after the fire started to get help. There was a huge outpouring of grief and support from the community, and a radio station ever raised money for the guy.
WELL, wouldn't you know that the husband started the fire after having a fight with his wife!
