This story isn't full of any "wow" factor but it really happened. My parents told me this and they don't make up stories.
It was July 1963 and they had just moved into a brand new house. New construction and they were the first owners. It was a 2-story house with the bedrooms upstairs. It was their first or second night living there and they had gone to bed. They were still awake when suddenly a door downstairs got slammed VERY hard. Nobody was down there and I was asleep in my crib upstairs with my parents. They had no air conditioning, windows were all closed and locked and the heat wasn't on since it was summer. It only happened the one time. I was only a year old so don't remember this but about 10 years later I had a lucid nightmare about 3 evil "hippies" hanging out in the same room where the door was slammed. At the time, I didn't know about the slamming door incident.
Later that room became my grandmother's bedroom and I was never comfortable in there. I wanted her to move to a different room because it just always felt cold, sad and well, evil.
They say that new construction and home renovations can stir the spirits. Maybe that's what happened. We lived in this house for 26 years and there were other oddities that mostly happened to me as a child. For a year or so, I would see a cylindrical column of a grey smoky haze that went from the floor to the ceiling just off the living room, always in the same spot. When walking past it I always walked faster...lol. Nobody else in the house ever saw it.
This house was on Long Island, NY, which was previously occupied by Native American tribes, Dutch and English settlers. This was the first "modern" house to be built on this land. Seems someone wasn't happy about that!
