When i woke up less than 3 hours ago at the time of writing, i felt something move(squirm violently) under me. At first i thought i had squished one of my housecats, but when i looked at it it was my own hand, completely numb and twitching. (it stopped squirming when it surfaced.) My first instinct was to grab it with my other hand and slam it into the ground near my bed and that did the trick i think, i got some control over it. I think it has something to do with sleeping on it because it was cold and out of circulation, and i got more control as the circulation returned.
