This happens to me alot. Ill go to sleep and wake up in bed unable to move. my eyes are open and it feels like my body is being pulled thru the center of the earth, up thru the house and thru the bed. the pressure is holding me down to the bed...but im awake the entire time.

othertimes i can see myself lying there and those times i feel weightless... but then it almost feels like i passout and wake up and everything is normal.

does anyone else ever get this? or can anyone explain it to me more?
