At about 3am...for some reason...I woke up terrified that someone was watching me sleep through the crack I my blinds. There was no hesitation..it was like I was sleep walking...I opened my eyes and jumped up... but my body didn't want to move other than fixing the window... it was like I was full of sand.... I hope it was just a one time thing.... I know that sometimes. People have these nightmare type of things...where they wake up...but are unable to move...it called sleep paralysis. Its something your body naturally does...while your in rem sleep...your body shuts down...but your mind still works...usually you open your eyes...but can't move...your brain doesn't send the signal to the rest of your body... what happened to me... it was like my eyes were open like in sleep paralysis...but its like my brain said...."keep that person from watching you sleep." ....and my body did it...  and I watched my body do it....like I was watching someone else...no control... but when I was done fixing the window...I was afraid I was going to collapse...I had no control... my body went stiff...and motionless...but I managed to fall backward onto my bed. Where I instantly went back to sleep... I was conscious during the whole episode...watching myself...but not controlling...reacting on impulse.....   I just read the wiki on sleep paralysis...and they say that it happens when people are under extreme amounts of stress. All I know...I was terrified that a person, a corpse or creature...was staring at me through the crack in my blinds....and I had to stop it.... anyone else ever have this? I had it once...but I wasn't moving...I saw things crawling on the back of my door...they had glowing eyes and there were hundreds...crawling all over themselves.
