I don't know...I live in a really old house (pre Civil War). I would think that dozens of ppl have been born and died in this house and I've never seen a spirit. Occasionally I see something on the main staircase, but if it's a ghost, it's the ghost of a small animal, probably a cat. I've never seen it any where else. One of the bedrooms gives me a creepy feeling, but that's about it. Oh, but, one time I thought I heard a child calling, "Momma," but that was before I had kids and I was a little freaked.
