In 1974, my family and I rented a house for a year while we were searching for a house to purchase. Many things happened during this 1 year stay. There were 3 bathrooms in this house, 2 in the main house and 1 in the outside servant's quarters. All 4 children were locked in at one time or another in the bathrooms. My personal experience with the 1 to 2 hour incarceration was very traumatic for a 10 year old. The bathroom door would not open. It was not locked and the door knob would turn but the door would not open. While I was on the inside, several people from the household was on the outside trying to open the door. Finally, after a couple of hours, the door just opened. This also happened to my siblings.
Several times during our stay, my great aunt would come stay the night. She said that during one of these stays in the late evening when everyone was asleep, she would hear the shower on and she would go and investigate thinking that one of us kids is playing with water. As soon as she enters the bathroom, the shower would stop and there would be no evidence that the shower was ever on: no water in the shower stall. While she was in one bathroom investigating, the shower in the other bathroom would turn on and she would go and investigate that. After finding the shower stall in the same state: dry, she knew that there was something going on in the house that is out of the ordinary.
My mother would also notice that in the mornings, all the closets would be wide open. She thought that the house must be tilted and the closet doors are opening due to gravity. To stop this, she put chairs in front of the closets to stop the doors from opening overnight. The one time she did this, she found all the chairs pushed away from the closets and all the doors where open.
My mother also lost a red cross pendant while we were in this house. She had a set of bright red jewelry which included earrings, a ring and a large red cross, about 2"-3" long. She usually keeps her jewelry set together so when she lost just the cross and not the earrings or ring, she was sure she didn't keep it in some other place. She searched the whole house and all possible nook and cranny that it could be in but couldn't find it. To this day, she still has the earrings and ring but the cross pendant was never to be found. After leaving the house and realizing that it was haunted, she "gave" it to whomever took it.
My father saw a shadow of a young boy walking around his bed and because he was half-asleep, thought that it was my brother. He asked the boy to go back to sleep and my mother was surprised because she said that my brother was asleep in their bed next to my dad.
My sister had bouts of sleepwalking while we were living in this house. She was never known to sleepwalk and has never done so after we left the house. We would find her behind the TV, in the hallway, etc.
The week we were moving out of the house, we left our laundry woman working in the outside servant's quarters while the main house was locked. She said that she heard someone playing with a basketball. Thinking that we were home, she went to the window where she heard the sound and couldn't see the ball or anyone inside the house. However, she could hear the basketball being bounced on the other side of the house. After knocking on the door and determining that no one was home, she also believed that the house was haunted.
Upon leaving the house, our neighbor's finally told us the story of the house. Apparently, the previous owners (not the owners we were renting from) had 2 children: a teenage girl and a young boy. While the parents were on vacation, both children were killed by their nanny while taking a shower. The nanny also preceded to bury the kids under the home's foundation. The bodies have been moved but there is a cement block under the house with the children's names on it.
