Three teenagers slip into a closed school after dark, chasing a dare that turns into something far stranger than they expected.
The air still held the damp, metallic smell of rain when Zosia, Michal, and Lena stopped beside the high fence of the old Primary School No. 7. The street behind them was bright with lamps, but the school sat in a pocket of darkness, its empty windows staring back at them like blind eyes.
It had been shut for years. People in the neighbourhood still talked about the gym ceiling that had caved in long ago, but nobody seemed to know what had really happened after that. The adults always went quiet when the school came up, which only made the rumours worse.
Michal found a gap in the wire and wriggled through first. Zosia followed, her pulse already racing. She kept glancing up at the upper floors, certain she had seen movement behind one of the windows, though she knew that made no sense.
"Remember what Kuba said?" Lena whispered, crouching behind a broken pillar. "That he heard laughter in the old cloakroom."
"He was trying to scare us," Michal muttered, gripping his torch so hard his knuckles had gone white.
They crossed the cracked yard and climbed the front steps, filming everything on Michal's phone. Proof for the rest of the class. Proof that they were not scared.
Inside, the silence felt thick enough to press against their skin. Their footsteps bounced off the walls. In the beam of the torch, dusty blackboards, peeling posters, and abandoned school bags flickered in and out of view, as if the building had only just decided to remember them.
Michal stopped at the top of the stairs. "Basement door," he whispered.
The staircase dropped away into darkness. Zosia looked at Lena. Lena looked back at her, and for one sharp second all three of them seemed to understand the same thing: they should leave.
Then they heard it.
A soft scrape from below.
Not a rat. Not the wind.
Something moving in the basement.
They went down anyway.
At the bottom, a long corridor stretched ahead of them, cold and black except for a faint green glow at the far end. It pulsed once, dimmed, and came back again, like a signal.
"That is not normal," Lena breathed.
Before anyone could answer, something rustled right beside them. Michal jerked his torch around, and a shadow slid across the wall, tall and thin and completely wrong for any of them.
