I was wondering has ever heard of this before and if it has a name. My brother has woken up on more than one occasion where his whole body was shaking and he said he still feels like he's sleeping and when he tried to move to shake himself out of it, he had no power over his body and couldn't even yell for help. He said he also felt at that time that he was floating out of his body towards the ceiling. He snapped out of it but he was really scared. His friend told him that she heard of a similiar situation in Japan where it caused people to die so now he's really scared of going to sleep. The only thing he does is drink and smoke weed but it's not alot. Has anybody ever heard of anything like this? Because he doesn't believe in going to the doctors and he won't budge on that so I'd really appreciate any information anybody might have. Peace and Love
