I never did until after my mother died.
People working in the house who had never met her or seen current pictures of her, reported running into her when working in the basement.
Had a few instances of something calling my name, with no one in the house, no tv's or radios on, and the dogs running into the living room to see who it was.
I don't know if it was a ghost, but it sure as hell was something going on.
