Have you ever thought about after you sleep? I mean what's going on when you sleep. You're in bed asleep, practically paralyzed and dead like. What if there is a killer about to kill you and you wont be awake or aware this is happening! Or a random Person in your house, you cant do anything, you are asleep not even thinking if you will ever wake up! So before going to sleep just think about what can go on while you sleep, or even wake up tomorrow!
