For some odd reason my girlfriend has been having sleep paralysis quite frequently these last two-three weeks. I'm on the lookout for it now so I try to wake her up if I see her paralyzed so she can snap out of it. But sometimes she snaps out of the paralysis and gets so scared she jumps onto me and wakes me up by scaring the shit out of me. But last night I was going to bed around 2-3am and woke her up as I was climbing into bed. She sits up and yells "WHERE IS OPTIMUS PRIME?!?!"
