since i was about 16 years old (i'm 22 now), sometimes when i'm falling asleep my whole body goes stiff, and i cant move a muscle even though i'm aware its happeneing, and i can hear fuzzy sounds and its like a vibration all over my body especially my head.. I cant open my eyes or talk and i can hear myself shouting what i want to say but nothing comes out. then suddenly, its like i jump out of it. which is weird, cos the only way i can describe it is like having a defribulater on me when i jump out of it cos i get a pain where my heart is, feels like an electric shock, as if its being started again. does anyone know what this is. the doc says it might be sleep paralysis, but is it so extreme as this? cos what i've read about it, it doesnt sound like it. sleep paralysis apparently is the none movement bit, but whats the rest of it??? id be grateful for anything you can help with. thanks so much.
