This happened several years ago, when I lived with my mother in an efficiency apartment in Northwest Washington DC. I never felt easy in that apartment, and then strange things started to happen.
The main room connected to the bathroom by way of a short hallway. Every time I walked down the hallway, I felt like I was being followed. Mom said the same thing.
There was also a hall closet where we kept our coats and jackets. Mom put a jacket in the cleaners one day and it somehow appeared back in the closet. We each thought the other had gotten it out of the cleaners but neither one of us had.
We also had a bed and a sofa in the main room. One night, I woke up and saw an arm sticking straight up from behind the sofa. Other people might say I was dreaming, but I KNOW I was awake.
We also had a large eat-in kitchen. I never liked it in there. I always felt uneasy. So, when I would close the kitchen door at night, I would be too afraid to reach in, so I would put my fingers in the crack of the door where the hinges are, and close it that way. One time I felt something very cold touch my fingers when I did this.
Also in the kitchen, once when the door was partially open, I saw what looked like a red cloth floating around in there, but when I opened the door completely, saw nothing.
All of these things my Mom has corroborated as well, but I never found out who or what was in that apartment.
Please let me know what you think. I have no way to prove any of these things but I remember them very clearly.
