When I was 14, my mother once again moved my family, me, my little sister, step sister and brother into the first home she ever purchased. The expense was cheap, and the year was 1989. The house was located right behind the school we attended, and graduated from.
Nothing happened or felt weird at first. For me at least. My little sister said she felt strange from the beginning, as if she was being watched, and never felt comfortable. The first thing that happened was the handle on my door would turn, the door would open slightly and close. It would continue to do this until I told it to stop. Then whatever it was would do it to my sister's door.
My mother would see shadow figures run across the bathroom wall. I've seen three shadow people by my bed. I just recently found out from my little sister she went to do her laundry when she heard me call her name up from the basement, and I wasn't home. She didn't do her laundry that day. I've heard my mother from the top of the basement steps when I was doing my laundry, and she wasn't home.
The attic window would blow out of the window frame on it's own and land on the roof. One time I heard my brother walk through the house before he got home.
