One time i had a false awakening. i was lucid at about 8 or 9 years old, lived in my ol' apartment complex.
I was having a horrible nightmare, then suddenly questioned its reality, and became lucid. for a while i was like wtf just happened? then i "woke up" only thing is, i woke up in my SISTER's bed.
Not my own. When i got up and tried to leave the room, the room suddenly started to feel more cramped and the air seemed to fog up and change color.
I tried to leave the room (cause by that point i was going out of my mind) and got thrown back against a wall. I tried to get through, but i would get thrown back.
I stood in the middle of the room and started to cry, but then froze up and for no apparent reason walked like i was possessed towards the door again. I got tossed again, and that time it struck blood, because when i saw it i screamed and woke up. for real.
