Horrid I. The Thumping Under the Floorboards is Rhythmic

The dust in the guest room didn’t settle; it hovered, vibrating in time with the sound.

Thump. Thump. Thump.

It wasn’t the erratic scratch of a rat or the groan of settling wood. It was deliberate. It was a wet, heavy percussion—the sound of a heart the size of a suitcase beating against the underside of the floorboards.

I stopped breathing, pressing my ear to the cold oak. The rhythm was infectious. I felt my own pulse slowing down, stretching out, struggling to synchronize with the massive, subterranean thrum beneath me. My chest began to ache with the effort of matching its pace.

That’s when I noticed the gaps between the boards.

They weren't filled with shadows. They were filled with hair. Thin, grey, human-fine strands were weeping upward through the cracks like rising damp, swaying to the beat. Thump. Thump. I grabbed a flathead screwdriver, my hands slick with a cold, greasy sweat. I had to know. I pried at the central board, the wood shrieking in protest, until it snapped upward with a bone-dry crack.

The thumping stopped. The silence that followed was louder than the noise—a vacuum that sucked the air right out of my lungs.

I leaned over the dark cavity, expecting dirt or pipes. Instead, I saw a pale, translucent membrane stretched tight across the joists, pulsing with a faint, sickly glow. Underneath the skin, a colossal, lidless eye rolled upward to meet mine. It didn't look like a monster. It looked like me—but older, decayed, and impossibly large.

It wasn't trapped under the house. The house was grown over it.

The "Thumping" started again, but it wasn't coming from the floor anymore. It was coming from inside my own skull. And as I looked down, I saw the grey hair beginning to sprout from my own fingernails, reaching down to join the rest of the carpet.
