It started with a rattle behind the grate,
a clicking rhythm that didn’t quite wait.
Maintenance said it was just old dust,
but we all smelled rust, sweat, and trust.
Then the nurse pulled back the metal plate,
and something fell with a sound like fate.
Not a screw. Not a bolt. Not a bone by guess–
just a human molar, stained and a mess.
We all stared too long, too still,
as if the vent might open and spill.
And when they reached in with shaking hands,
they hit something soft that didn’t withstand.
They found a tooth in the vent, and nothing’s clean,
no scrub can erase what’s been unseen.
You can patch the grate, but the breath still stinks–
of skin and silence and something that thinks.
It’s not gone.
It just shrinks.
Next day, someone scratched the wall,
“Look inside,” in letters small.
And when the nurse checked the filter slot,
she pulled out hair tied in a knot.
Someone’s files went missing next,
Patient Twelve, room notes untext.
No discharge. No transfer. Just gone–
but her breath still fogs the lights at dawn.
I heard a whisper when I tried to sleep,
through the slats where secrets creep.
It said, “I fed the dark with everything I meant–
and I left my truth in the vent.”
Now they clean less often near that wall,
and the hallway dims before nightfall.
And every shift, someone new goes pale,
when the grate starts to rattle like a nail.
