I'm usually already out of bed sprinting at whatever it is. It's happened before where I'd wake up and think I see a silhouette. It's not that I'm trying to be brave, I've just seen enough horror films to know that first you see the monster, then the monster scurries toward you. I don't think I could handle seeing some crazy shit like that, so the best way to beat fear is to beat it into submission. Take it out before it takes you out, that's what goes through my mind. Something similar happens when my someone calls my name to wake me up. I go from asleep to out of bed and standing in half of a second, as if sleeping is a crime or something lol.
