sleep help: My friend has, uh, violent reflexes when someone tries to wake him up… - Help.com

Doesn’t need to be choking or pulling weapons out on somebody to be pretty bad… He’s nearly knocked his dad into the bedpost one time, and another kicked someone into the door or something, which knocked it off its hinges…

Something like that would not be good at all if he had little kids running around, or someone not very sturdy… I remember when my half-sister was visiting with her kids, my niece tried to wake my dad up while he was sleeping on the couch and he almost knocked her off her feet. If she would have fallen, she would’ve hit her head on the coffee table behind her and probably busted her head open. :/
