I firmly believe one thing: every problem has a reasonable explanation. You might not find it right away, but that doesn't mean it doesn't exist. That's my survival rule in this line of work.

I work as a night janitor at MIT. Yeah, that MIT. The place is crawling with geniuses, and my job is to clean up whatever mess they leave behind. My entire work routine is a battle system against chaos. Disinfectant mixed at exactly 1:99 with water, mop angle precisely calibrated, trash meticulously sorted. This isn't just cleaning—it's maintaining the fundamental order of the universe.


These brilliant minds can launch rockets into orbit but can't figure out which bin is for paper recycling. Every damn night I find soggy tea bags and takeout containers in the paper bins. They call it focusing on "more important things." Whatever.

I work in Building 32, the famous Stata Center. You know, that architectural fever dream that looks like someone stacked blocks while drunk. Tonight, I'm down on the second basement level, connected to the boiler room and maintenance pipes—a place most people don't even know exists.

I push my cleaning cart with its signature squeaky wheel—that persistent sound my only companion in these empty corridors. I'd just finished mopping and was about to call it a night. That's when I stopped dead in my tracks.


There was an extra door on the wall.

This sounds ridiculous, I know. But that's exactly what happened. On the wall to my left stood a dark gray metal door where white tiles should have been.


I am one hundred percent certain there was no door here last night. I walk this exact path every shift and know every detail by heart. That corner tile with the lightning-shaped crack I always notice? Gone. Along with the surrounding area, all replaced by this door.

My brain kicked into overdrive.

Possibility one: I'm wrong. Years of night shifts have screwed with my biological clock, so memory glitches happen. Maybe I'm mixing up yesterday with last week.

To verify this, I pull out my phone. My gallery's packed with thousands of pictures—mostly of my cat Whiskers—but occasionally work stuff too. I frantically scroll through, searching for anything showing what this wall should look like. Nothing. Turns out I don't make a habit of photographing random walls.

This possibility: inconclusive.

Possibility two: New construction. Some department installed a door and—shocker—didn't bother notifying maintenance. Classic MIT, where interdepartmental communication is about as straightforward as quantum physics.

This explanation makes sense. I step closer, examining it for clues. The door is metal, dark gray, and cold to the touch. No markings whatsoever. No room number, no "Authorized Personnel Only" sign. That's against regulations—every functional door needs proper identification.

Looking closer, I notice a strange symbol etched into the door panel. Not any company logo or directional sign I've ever seen. Half circuit diagram, half tribal marking, with complex lines that make my vision swim when I focus on them.

I unhook my master keys from my belt but quickly realize they're useless. The door has no keyhole, no handle. Just a solid slab of metal.

So much for possibility two. What kind of door has no way to open it?

I rap on the panel with my gloved knuckles. The dull thud confirms it's solid, not hollow.

My logical chain of thought hits a wall. Nothing in my experience explains what I'm seeing. It defies reason.

I decide to let it go, log it in my report, and email my supervisor tomorrow. Just as I turn to leave, something stops me.

My eyes drift back to that door.

A completely irrational thought creeps into my mind.

I reach out, pressing my palm flat against the cold metal, and give a gentle push. I don't actually expect anything to happen—just completing the logical sequence of investigation.

The door, without so much as a whisper, swings smoothly inward.

I snatch my hand back, heart lurching in my chest.

Beyond the door lies absolute darkness. Not the ordinary darkness of an unlit room, but something dense and textured that seems to devour light itself. My phone's flashlight beam doesn't penetrate it—the light simply vanishes, swallowed whole without even revealing the edges of whatever space lies beyond.
