I've lived in the same village for many years. Moved away briefly in my early twenties but moved back with my husband. As a teen I babysat for many of the young families here.
I was babysitting for a family for the first time. One of the parents was a renowned, and well-off, surgeon. The house was lovely. And old. And huge. And detached.
I remember even the front door was fascinating. Huge and thick. If you looked at the width of it, you could see layers where it had been built up over the years.
They had two daughters. Their rooms were at the top of a flight of stairs at one end of the house. There was another flight of stairs at the opposite end of the house which led to the parents room.
The lounge was downstairs in the middle of the ground floor with an open passage that ran along behind it linking the house.
Once the children were in bed and fast asleep, I decided to make myself a cup of tea. I went into the kitchen where they had a big walk-in pantry. I got milk out the fridge which was in there, shut the door and waited for the kettle to boil. But as I was waiting, one of the children had gotten up and was wandering around in the parents room (there was a door that connected the parents end of the upstairs to the children's end). I went up the parents side staircase and the footsteps stopped, but there was no one there. The door to the other side was locked.
I went back downstairs and the door to the pantry was wide open. I shut it and abandoned my cup of tea.
I sat in the lounge and it just felt like someone was watching me from the corridor behind me.
I heard the footsteps again. Not light but completely deliberate. Like someone with boots on. I felt I had to check on the children. They were fast asleep and absolutely fine.
When I came downstairs again, the cushions from the sofa were on the floor.
I was so freaked out. This was before the era of mobile phones and the house phone was at the bottom of the parents staircase and I was too afraid to go over there to use it.
I moved one of the chairs so I had my back right up against a wall. The footsteps continued for hours.
At 12:05 the TV went to static and went off.
They didn't come home until 3am and I never babysat for them again. I have never before or since been so absolutely petrified.
