I was 13 at the time and at a friend's house. His sisters room was down in the basement and there was an entrance at the end of the living room. She was showing us how her horse ribbons kept turning upside down. She turned them right side up and tried to move them by waiving her blanket. They didn't budge. We were there alone and we heard someone walking upstairs in the kitchen above. We looked at each other and as I was about to ask if their mom was home, we heard a chair slide across the floor from the kitchen, through the living room and fell down the stairs into the basement. We couldn't move!
Another time, at the same house, we were doing our homework and we heard footstep on the roof. As he looked at each other, the dryer started going while it was unplugged.
When they moved out because of other strange things that took place, the landlord asked if they were moving because of the ghost. They were shocked and explained the things that had happened to them. He explained that the owner before him was an elderly man who walked in and surprised two unsuspecting thieves. They dragged the old man down to the basement, tortured and killed him down there.
Wow, I still get chills thinking about that!
