I was laying in bed, sort of awake.. and out of nowhere - my body locks up, I start shaking. I'm numb.. I can't see, I can't hear (sounded like loud rumbling and symbols clashing nonstop). I can't move, I can't talk. All I can do is lay there. Things were flashing before my eyes.. I don't remember exactly what they were, but I was seeing things. When I try to remember what I saw all I remember is a blur. It was hard to breathe.

This went on for what seemed like several minutes, and finally ended when I forced myself to yell.

..can anyone tell me what happened? I am scared to go back to sleep..
