Hi, im 16 and tonight I had an extremely horrible experience. It happens during my sleep usually in a dream but its extremely vivid and I seem almost half asleep and half awake. Tonight I was dreaming I dont remember what but I remember everything going white like blinding white it felt like my eyes rolled back and then I started shaking violently but idk if it was in my dream or not. I remember hearing loud screaming but it wasnt me because I couldnt talk or move during this I woke up with my mouth wide open and my tounge hangin out of my mouth. I feel very confused and scared as this happened within the hour. Can someone relate or maybe are these symptoms?
