This happened to me when I was in high school, between 1999-2001. My family and I rented a home that was converted into two apartments. My brother and I shared the one-bedroom upper, and I took the back bedroom.
I had just gotten into bed one night, and was settling in, when all of a sudden, it felt like something wrapped a hand around my ankle and yanked, really hard. I let out a scream and sat up in bed, only to find no one in my room. I tried to write it off as the folded laundry on the end of the bed, falling on my legs, but upon examining the pile, I found that it was leaning to one side, but not enough to simulate someone grabbing my ankle. The experience freaked me out pretty bad.
I experienced other minor things in that upstairs apartment. Sometimes at night, I thought I heard someone coming up the stairs, but upon getting up and checking, there was no one there, and my brother, who was a sleepwalker as a child, was still in bed, in the same position I had left him in when I put him to bed.
There was a door in my bedroom leading outside to a wooden fire escape. I would sometimes hear something tapping on the glass. There are trees that hang over that deck, so I would get up to see if it was something like that, but the branches were too high to reach the door, and there was no evidence of a person or animal being up there.
My family and I promptly left that house in 2002.
