Ghost Stories

I remember as a child growing up, my Mom telling us ghost stories.  I would be so scared that I would sleep with my head under the covers.  I still remember some of those stories.  My husband past away 4 years ago and some times I can still smell the cigarette smoke as though he was here.  We were discussing ghost stories at the office this morning and I was surprised that other people had their own ghost stories.  Two of the girls said that they can hear noises in their home that can not be explained.  One said that when she takes pictures in the house you can always see a strange image in the photo.  Strange, but maybe there are things lurking in the night!
