Nice name. Can I still call you Marx?
I'll redo my story, and Rio helped with the extra end bit.
The Nightmare
It was the night before Halloween, and Sampphire Frimn was staring out of his window, bored. He wore a green top, with blue jeans, and white trainers. His hair was brown and his eyes were blue. Across the road from his house, was an abandoned shack, it had been empty for years. There was a story about this shack that anyone who dared enter it, disappeared. Sam didn't believe the stories. It wasn't raining, and his mother would be home late, so he decided to take a look at it. Not the usual story you come across, since the entrants are usually in groups, and they plan beforehand. But this would be far worse, something even more terrible than the Bogeyman. Sam crossed the black asphalt road, towards the wooden shack. He unlocked the padlock with a tug on it. The door swung open. It had an eerie feeling to it. There was one door right across from him. It creaked open slowly. There was a chair. As Sam entered, he noticed nothing else. He saw nothing else in the room. He sat in the chair, feeling slightly cocky. The door slammed shut. Sam ran over to it and tried to open it, but to no avail. Feeling like he had no choice, he went over and cautiously sat in the chair. Then, a shadowy figure appeared in front of him. The shack went black and an ear-piecing scream came from within…
Thirteen years later (this was Sam's age) he was found, tortured and left completely mad in the dessert. He never recovered and died soon after he was found.
That hut was actually exists. Down the road from me and Rio there is a shack, just like the one I described. They say people go missing if you sit in the chair on Halloween's eve.
