My mom and my brothers were sure we lived in several haunted houses. In Ohio, we lived in a house that was near a place where there were frequent fatal automobile accidents. We had ghosts(we thought were possibly kids that had died in a wreck nearby) that loved to play the nintendo at night. My mom also saw various decayed indians wandering around the house at night.
In Georgia, we lived on a civil war battlefield so we had 1-2 civil war soldiers in our house. One of those soldiers served as sort of a sentry. He'd flip on light switches, etc. whenever we had people wandering around outside at night. My brother also ran into an old woman in our hallway at night once when he was on his way to the bathroom.
Now I don't believe in ghosts anymore and doubt my own experiences and what happened to my brothers/mom. I just happen to love ghost stories.
