happened to me, i had smoked at about 1am or so with some friends, then ended up passing out later. then i woke up and the clock said 530, and i swear i heard lots of voices in my room and i could not move any part of my body. then after about 30 seconds, it went back to normal, and i could move and didnt hear anything. it was the second time i had smoked, and it was one of the weirdest sensations ive had.
