Here's one for you.
I owned an old colonial home(early1800's) in NH. After buying it a few people, told me I had purchased the haunted house in town, but didn't think anything of it. Shortly after buying it I heard the sound of something bouncing down the back stairs. I looked up you could hear an item bouncing down the stairs then hitting the wall where the stairs turned 90 degrees. The next time I was vacuuming downstairs in a room adjacent to the space that the stairs came into I found a marble. The sound and the marble finding went on and off for a couple of years. I inquired to a couple of previous owners going back 50 years or so if they had heard ghosts or strange sounds at all. They had stories of chairs moving, a piano being played. I was told a story about the people I purchased the house from and how the wife had seen a little girl looking out a window in the room next to the back staircase. During 1996 I had a women helping me design some product packaging, she came over to show me the proofs. When I opened the door for her to come in she said you have a presence here. I kind of looked at her and said oh really where? We wandered about the house until we came to one of the large bedrooms as I opened the door she said there's an old women over in the corner crouched on the floor. I couldn't see anything there, but some weeks earlier I had heard footsteps in that room when I was stoking a fire in the fireplace in the parlor below that bedroom. I was certainly freaked out, but I was never approached nor did I see any apparitions during the 20+ years I owned the house. I sold the house in 2006 and have owned two old houses since with no sounds, ghosts or whatever since. I still have the marbles sitting in a pewter dish. During 1997 or 1998, around Halloween I was watching TV, the local station was going to be interviewing the high witch for NH. When segment opened it was the same women that had been designing the packaging for me. I had no idea she was any kind of witch, other than she could sense ghosts.
