What happened???? I was sleeping unable to move but i could hear my frend telling me to wake up then i did!!!!?

Do a search for sleep paralysis, I think you will find your answer there. The way I understand it, in sleep paralysis, basically your mind wakes up before your body does, and you wind up feeling paralyzed, people get a little freaked out about that, cos they don't know what's going on....good luck...
