I used to inspect abandoned subway tunnels. I quit after checking the security cameras.

My name is Ethan, and I used to think the scariest thing about New York City was the rent. I was wrong. For three years, I worked the graveyard shift as a night inspector for the MTA, checking the structural integrity of the old, abandoned subway tunnels beneath Manhattan.

It’s a lonely job… just you, a flashlight, and miles of cold, dripping concrete. You get used to the shadows. You get used to the rats. But you never get used to the silence.

On the night of March 14th, I was assigned to Section 4—a deep, forgotten tunnel line closed since the 1970s. The only way in was through a heavy, industrial steel door secured by an old digital card reader.

To enter, you swipe your ID, the scanner beeps, and a tiny digital screen flashes: “USERS INSIDE: 1.”

I swiped my card. *Beep.* The screen lit up. But my breath caught in my throat. The pixelated green text read: “USERS INSIDE: 2.”

I stared at it. That was impossible. No one else was scheduled for Section 4. I assumed it was a glitch—the system was decades old, after all.

I pushed the heavy door open, stepping into the damp, freezing air of the tunnel. The steel door slammed shut behind me with a loud, metallic echo that seemed to travel for miles. *Clang.*

I switched on my high-powered flashlight, cutting through the thick, heavy darkness.

I started walking down the tracks, the gravel crunching beneath my heavy boots. After about twenty minutes of walking, I stopped to log a cracked wall beam.

That’s when I noticed it. The echo of my footsteps… didn’t stop when I did.

*Crunch.* One extra, distinct step echoed from the darkness behind me.

I spun around, throwing the flashlight beam down the tunnel. Nothing. Just empty tracks disappearing into the black void. “Hello?” I called out.

My voice bounced off the curved walls… *Hello… hello… hello…* Then, from the absolute darkness just beyond the reach of my light, came a response.

It wasn’t a word. It was a rhythmic, wet, clicking sound… like a fingernail snapping against steel.

*Click… click… click.* And then, a wave of pure, putrid stench hit my face. It smelled of rotting copper and damp, stagnant earth.

Every instinct in my body screamed at me to run.

I turned and began walking back toward the exit door, fast.

My flashlight beam was shaking violently now.

I pulled out my company radio, pressing the button. “Control, this is Ethan in Section 4.

I think someone else is down here. Code Blue.” All I got back was a wall of harsh, deafening static. But beneath the static… I could hear that wet clicking sound, coming right through the radio speaker.

I clipped the radio back to my belt, my chest heaving. To calm my nerves, I pulled up the live security feed of Section 4 on my company phone.

The camera was mounted directly above the exit door

I was walking toward. I opened the app, waiting for the night-vision feed to load.

When the screen flickered to life, I stopped dead in my tracks.

The camera showed the heavy steel exit door. And standing directly in front of it, looking up into the camera lens, was me. It was my jacket, my build, my flashlight. But it couldn’t be me—I was a quarter-mile down the tunnel.

The thing on the screen slowly raised its arm, waving directly at the camera with a jerky, disjointed movement… like a puppet with broken strings.

I stared at the screen, my mind fracturing with terror. Then, the thing on the video stopped waving.

It slowly turned its head around—a full 180 degrees—and looked back down the tunnel.

Toward the camera. Toward *me*.

On the tiny phone screen, I watched myself… drop to all fours. Its limbs bent backward with loud, sickening cracks.

And then… it began to sprint down the tracks toward my position, moving with the terrifying, spider-like speed of a starved predator.

I dropped the phone. It shattered on the gravel. I turned around and sprinted deeper into the abandoned tunnel, my heart exploding in my chest.

Behind me, the sound echoed through the dark… the terrifyingly fast, heavy thudding of hands and feet slapping against the wet stones. *Thud-thud-thud-thud.* It was catching up.

I ran until my lungs burned like fire. Up ahead, I saw a rusty maintenance ladder leading to a street-level gratted vent. I scrambled up the iron rungs, gasping for air, not daring to look down.

I threw my back against the heavy iron grate, screaming for help into the empty New York street above. Miraculously, two police officers patrolling the block heard my screams.

They pried the grate open and dragged me out into the cold, sweet night air.

I collapsed on the concrete, sobbing, pointing at the dark hole below.

The police called for backup and searched Section 4 for hours. They found nothing. No intruder. No monster. Just my shattered phone lying on the tracks.

They wrote it off as a severe panic attack brought on by isolation. I resigned the next morning.

It’s been a year since that night. I moved out of New York, bought a small house in the quiet suburbs of Ohio, and took a remote desk job.

I thought I had escaped the tunnel. I thought I was safe.

But three days ago, I had to replace the batteries in my house’s smart thermostat. To sync it, I had to log into the main security hub app for my home’s digital locks—an app I hadn’t opened since I moved in.

I connected the device, and the screen refreshed, displaying the status of my house.

My blood turned to ice. The digital display read: “LOCATION: MAIN HOUSE. ACTIVE ID CARDS: 1.”

But right below it, under the system log, there was a notification from the day I moved in. A green, pixelated line of text that had been sitting there in silence for twelve months. It read:

“USERS INSIDE: 2.”

Last night, I woke up at 3:14 AM to a sound coming from the dark vacancy of my crawl space beneath the floorboards. It wasn’t a footstep. It was a wet, rhythmic clicking sound… right beneath my bed.

And as I lay there, frozen in pure horror, my phone on the nightstand lit up with a text from my own number:

“Thanks for swiping us out. It’s so much bigger out here.”
