This happened to me seven years ago and to this day, I still can't sleep with my legs stretched out so that my feet are near the end of the bed. I went to bed that night just like I would any other night, nothing out of the ordinary, only I awoke at 3:00 a.m. to something grabbing and tugging on my left foot. When I opened my eyes and began to sit up, what ever it was let go, my first reaction was to start yelling at my little brothers for waking me up, but then I realized that my door was still closed and if it had been one of them, I would have heard them running out or they would be standing in there with me.
I slept on a mattress on the floor (white trash I know) so no one could have hidden under my bed. My closet didn't have a door and was so crammed full of stuff that no one could have hidden in it, still thinking that it was somehow one of my siblings, I turned around to look at the clock, it was 3:00 am, this may or may not be important but it is a little odd that ever since then, I wake up every night around 2:30-3:00. Since I was still half asleep and had ruled out anyone in my house as the culprit, I just went back to sleep, which is a little odd since the next morning upon waking up I remembered what happened and was very freaked out and still had no idea what could have grabbed my foot.
There was firm pressure like a hand and the tugging was hard enough to wake me up and it didn't let go until I actually started to sit up, so I really don't think this could have been a dream. Sleep paralysis is something I have experienced a number of times and this was nothing like any of those experiences. I would love to know what other people think this may have been.
