Chapter one: A solid wall

A 19-year-old guy called Jason walked down the street, chuckling. Less than a minute ago, he was having a drink in a bar with his friends. They had been joking around, until a random guy told them to shut up. Since it was already nearing midnight, the guys decided to leave for their respective homes. Brad had made one last quick joke before they all departed, and it was still echoing in Jason's mind.

"Those jokes you make, Brad…" Jason quietly chuckled.

Then, something happened: a figure ran by, stealing Jason's keys from his pocket in the process. With a speed the young man could barely comprehend, the figure turned to his right and ran down a small alleyway. Jason, whose reactivity had degraded slightly because of the beer he drank, shouted and ran after the figure.

"Come back here, asshole!" he yelled as he ran his ass off, trying to catch this person, get his keys back and report this sonofabitch to the cops.

The alleyway ended soon enough. However, something wasn't right. Despite the absence of any ladders, drainpipes or anything of the sort, the figure was nowhere to be seen. How was that possible? Even with their speed, they couldn't have slipped past him, could they? This place was too narrow for that.

Unable to do anything else here, Jason decided to head back. He turned back to where he came from…

…only to walk against… a solid wall?

How? Mere seconds ago, he just walked – or ran, rather – through that alleyway without any trouble. Where did this wall come from? It seemed to be connected to the houses on Jason's side, as if it had always been there. It was even made of the same material: bricks and cement.

Then, something else happened: the wall of the house on Jason's left slowly began to move towards the wall on his right. The 19-year-old gasped; he was about to get crushed! He attempted to scream, but something seemed to block his throat, only letting a raspy whisper pass.

He could not even make a sound when the two walls were mere millimeters from him without stopping. The young man silently cried in agony as the walls mercilessly crushed him.

The last thing he saw before he died was a face, looking at him maliciously from the roof of one of the houses.
