sometimes when i wake up, my body will paralyze. i cant call out or move or anything. its talk a long time before i can get up. I can hear everything going on around me but at the same time i hear other things. this has ben happening for three years now. i have not seeked medical attention. and this happens quite often. im 17 years old. It feels like im dying while im awake. its a strange feeling like a mid death syndrome.could this be serious?
