At the 0:12 mark, a door at the end of the hall creaked open. No one walked out. Instead, a hand reached around the frame and began to smudge charcoal against the wall, drawing a series of tall, jagged tally marks. One, two, three, four—then a long diagonal slash for five.

Elias paused the video. He felt a sudden, sharp chill. He turned around and looked at the wall behind his desk. There, etched into his own wallpaper in fresh, dark soot, was the exact same symbol: four vertical lines and a slash. 3701_5.mp4

A second later, his power cut out. In the sudden pitch black of his apartment, the only thing he could see was his laptop screen. The video was no longer showing a hallway. It was a live feed of a dark room. In the center of the frame was a man sitting at a desk, staring at a glowing laptop screen with wide, terrified eyes. Elias realized he was looking at the back of his own head. At the 0:12 mark, a door at the end of the hall creaked open

He didn't turn around. He just watched the screen as the blurred face leaned into the shot, hovering just inches above his shoulder. The video ended, the screen went black, and the hum finally stopped. One, two, three, four—then a long diagonal slash for five

When he finally hit play, the video opened to a static shot of a narrow hallway. The walls were a sickly, hospital green, lit by the rhythmic strobing of a dying fluorescent bulb. There was no sound except for a low-frequency hum that made Elias’s teeth ache.

On the screen, the door behind the "on-screen Elias" began to creak open. In the real world, the floorboards behind him groaned.

He looked back at the screen. The video was still paused, but the timestamp was moving. 0:37. 0:38. In the frame, the hand was gone, but the door was wider now. A dark shape began to lean out—a face with features that looked like they had been blurred by a shaky camera lens.
