The man in the video paused. He slowly turned his head toward the "camera."

At the 0:42 mark, a hand entered the frame. It didn't reach for the milk. Instead, it began to meticulously peel the wallpaper off the far wall, strip by strip. Behind the floral pattern wasn't drywall or wood. It was another room, identical to the one in the video, seen through a narrow gap.

Elias froze. The man in the video wasn't just a recording; he was wearing the same headset Elias was wearing. He was sitting in the same chair.

He looked down. The file size of began to grow, byte by byte, recording him in real-time.

He clicked it. The player opened to a grainy, low-bitrate shot of a kitchen. It was unremarkable—a bowl of fruit on the counter, a ticking clock, a half-empty glass of milk. But there was no sound, only a low, rhythmic thumping that seemed to vibrate the speakers without making a noise.

On the screen within the screen, Elias saw a tiny version of himself leaning toward the monitor. A cold realization washed over him: the file wasn't a recording of the past. The "thumping" sound wasn't static—it was the sound of someone knocking on the floorboards directly beneath his feet.
