nightmare

I was lying on my bed and fell asleep:

I wake up but can't move and I start to panic. There is someone on the right of the bed trying to roll me over to do something, I try hard to wake up but it doesn't work, so I start screaming my brother's name to come help me wake up, but he isn't coming. I try to calm down and close my eyes to fall asleep, but instead I woke up.
