You turn around and run back to your home. You can hear the other kids laughing at your cowardice. You don't stop until you're back home and away from that place. the next day, you hear people talking about how John hasn't been seen since he walked into that house last night. You know John died in that house. You're not sure how or why you know that John is dead, you just do.
That night, you have a nightmare. You're in that house and you're running from something, but you're not going anywhere. You're running on a sheet of ice on the ground. No matter how much you try, you can't get off the ice as that something comes closer.
You fall out of bed. Your heart calms long after you realize how you know John is dead. You even realize that house is taunting you, telling you it will take you when it wants.
