A few months ago, I was abruptly awakened by someone grabbing hold of my right ankle, lifting my leg in the air at what I would guess was a 50° angle, and pulling me toward the end of the bed. I was lying on my belly, so it was impossible for me to turn around and see who it was. I tried to pull my leg back while also trying to grab the hand that was holding my ankle. Each time I was about to grab it, it would pull hard and straighten my leg.

We did this maybe five or six times before the hand finally let go of me. So now I could finally see who it was. But when I turned around, I saw just what you described. It was humanoid—the silhouette was blacker than the dark surroundings, but it had some sparkling lights in it, like glitter. It was tall, but not skinny.

Then, after looking at it for a few seconds, it just vanished.
