One night around 1 AM, when I was about eight years old, my mom woke me from sleeping on the couch. She was pale and seemed to be very frightened. "Go to the car while I grab my gun." (she had a license.) I followed my mother's instructions. Now, keep in mind, when we left, the back door was shut and locked, and the dog was inside.
As we got in the car, my mother explained what was going on. Apparently, she heard noises coming from upstairs. She heard what sounded like footsteps and chains. We lived in the house on the corner so we could see the backyard from the street. My mom figured someone had broken in somehow, like maybe climbed a ladder or something to the second floor. So, we took a peek. But we didn't see an intruder. Instead we saw the dog running around outside. The door was locked and he was inside. My dad worked graveyard so he wasn't home at night. We knew it wasn't him making noises. We had no clue what to do so we called the cops.
We were too scared to go into the house so we waited for the cops. We followed an officer upstairs but there was nothing there. My mom heard the closet door sliding back and forth but the doors were closed. We had always heard and seen things in the house but never anything like that. It scared my mom so much that when we came home at night we went through the house and turned on all the lights. Again, I have always heard things, but never encountered something like this. This story was completely truthful.
