One day after school you decide to take your dog on a walk, your dog runs off, into the barrens and you have to chase after her/him. you run after her/him as fast and you can but while running through the grey water trip and fall, when you look up your dog is no where in sight but then.. you see a red balloon float down towards you, it gets very close to you then pops to reveal a bloodied clown with razor sharp teeth. you jump up and run as fast as you can, you see the light of the outside again but see a what seems to look like some kids you recognized from school, before you know it you're right in front of them and they look over to you, you can't stop running and collide with one of the kids....
