A coworker I barely know left a resignation letter on my desk this morning and it was addressed to me

I work in a mid-sized insurance company on the third floor of an office building that was built in the late seventies. I have been at this job for five months. I sit in a corner desk near the emergency exit. It is not a good desk. The overhead light flickers. The heating vent above me makes a ticking noise that facilities has looked at twice and called normal. But the rent in this city is what it is and the job pays decently so I show up and I sit at the desk and I do my work.

This morning I arrived at 8:15 like I always do. There was a sealed envelope on my keyboard. White. Standard letter size. My first and last name written on the front in blue ballpoint. No department. No company header. Just my name.

I opened it. Inside was a single typed page. I am going to reproduce it here as closely as I can because I have read it enough times now to know most of it from memory and the letter is sitting in my lap as I type this.

“This is not a formal resignation letter even though I am resigning today. This letter is for you. I am sorry I did not write it sooner.

I have worked in this building for four years. In that time I have watched three people sit at the desk you are sitting at now. I am in a different department on a different floor but I pass your corner every morning on my way to the stairwell and I have learned to watch that desk the way you watch a trap you cannot disarm.

The first person lasted eight months. The second lasted five. The third lasted eleven weeks.

By the time you read this I will be gone. I cleared my desk last night after everyone left. I cannot be in this building anymore. I cannot walk past your corner one more time and say nothing. So I am saying it now and then I am leaving.

The lights above your desk will flicker. They already do. You have already mentioned it to someone. I know because everyone who sits there mentions it within the first two months.

You will start losing small pieces of time. Nothing dramatic. You will look at your computer clock and twenty minutes will have passed that you cannot account for. You will assume you were focused on work and lost track. You were not focused on work. You were gone. Not asleep. Not distracted. Gone. The gap will feel like nothing because you will not have any memory of it. It will just be twenty minutes later than it should be and you will blink and move on.

This has probably already started. Check your sent emails. Look for gaps between timestamps. You will find windows where you apparently did nothing for fifteen or twenty minutes in the middle of a workday. No sent emails. No saved documents. No browser history. Nothing. You were at your desk. Your badge did not log you leaving the floor. But for those minutes you were not there.

Then the dreams start. I am not going to describe them because the last person I tried to warn did not take me seriously until the dreams began and then she could not stop talking about what she saw in them and talking about them is what made it faster. Do not describe them to anyone. Not a friend. Not a therapist. Not online. The dreams are how it maps you. When you talk about them you are giving it a signal to follow. Keep them to yourself. I know that is difficult advice. When the dreams start you will want very badly to tell someone. That urge is not yours. That urge is part of it.

I do not know what it is. I have spent three years trying to find out. The building was constructed in 1978. Before that there was a smaller office building on the same lot. Before that there was a house. I could not find records on the house. The county office said the records for that parcel were damaged in a basement flood in 1991. I do not believe that. I believe someone removed them.

The desk you are sitting at is positioned in the corner of the building that corresponds to a specific room in the original house. I do not know what happened in that room. I only know that whatever happened left something in that spot. Not in the building. In the ground. Beneath the foundation. In the dirt under the concrete under the carpet under your chair. It is below you right now. It has always been below that desk. The building was built on top of it. I do not think the builders knew. I think it was already waiting when they poured the foundation.

The three people before you all left the company. The first one quit and moved out of state. I found her on social media. She does not remember working here. She does not remember the desk. She does not remember the dreams. She has a two-year gap in her resume that she cannot explain and she has posted about it publicly and she seems confused by it in a way that does not look like someone who simply forgot a job.

The second one was terminated for performance issues. He started falling asleep at his desk. Every day. Multiple times. He could not stop. He told HR he was not sleeping at night. They suggested medical leave. He refused. He said he was afraid to sleep at home because the dreams followed him there and he felt safer sleeping at the desk. He said that out loud to his manager. They let him go the next week. I saw him in the parking lot on his last day. He was sitting in his car staring at the building. He sat there for four hours. I watched from the window. He did not start the engine. He just sat and stared. Then he drove away and I never saw him again.

The third person is still in the building. You know her. She works on the fourth floor. She has dark circles under her eyes that never go away. She has worked here for two years since transferring from your desk. She asked to be moved. She did not explain why. They gave her a different desk on a different floor. The dreams stopped when she moved. But she does not sleep fully anymore. Not ever. She told me once in the stairwell that she figured something out about the dreams. She said if you keep one eye open you do not go all the way under. You stay on the surface. It cannot reach you on the surface. Only in the deep. She has not closed both eyes at the same time in two years. She sleeps with one eye open every single night. She is exhausted permanently. But she is still herself. That is more than I can say for the first two.

I am not brave enough to stay. I am not brave enough to sleep with one eye open for the rest of my career. I am barely brave enough to write this letter.

If you want to talk to someone who understands what is happening to you, find the woman on the fourth floor. You will know which one she is. She looks like she has not slept since the day she was born. She will not want to talk. But she will. She has been waiting for someone else to sit at that desk so she is not alone with what she knows.

I am sorry. I should have said something on your first day. I was afraid that saying it out loud would make it notice me. I am on a different floor. Different corner. It has never reached me. I want to keep it that way. That is the truth of why I waited. I was protecting myself. I am not proud of it.

Please do not try to find me after today.”

There is no signature. I read the letter three times at my desk. Then I did the first thing it told me to do. I checked my sent emails. I went back through five months of timestamps.

There are gaps. Fourteen of them. Windows of ten to twenty-five minutes where my sent folder is empty, my browser history is blank, and my badge shows no movement. I was at my desk. I was logged in. But I was not doing anything that left a trace.

I did not notice any of them until today.

I went to HR at 9am. I asked about the person who left the letter. They confirmed the coworker resigned effective immediately. No notice. No reason provided. Desk already cleared. Badge returned. Gone.

I asked about the previous people who sat at my desk. HR said they could not share personnel details. I asked if the desk had high turnover. The woman behind the counter paused and said “some desks just do not work for people” and looked away.

I went to the fourth floor during lunch. I walked the entire floor slowly. I found her in a cubicle near the far wall. I knew it was her before I saw her face because the woman sitting next to her was leaning away slightly. Not consciously. Just a few inches of extra space. The way your body moves away from something without telling your brain why.

She looked exactly like the letter described. Dark circles so deep they looked structural. Not like someone who missed sleep last night. Like someone who has been running on half-sleep for years and it has settled into her bones. Her left eye was slightly more open than her right. Not dramatically. Just enough that if you were looking for it you would see it.

I sat down across from her and said “I sit at the desk on the third floor. The one in the corner by the emergency exit.”

She did not look surprised. She closed the folder she was holding and looked at me for a long time. Then she said “how long.”

Five months, I said.

“Have the dreams started.”

No, I said.

“They will. Probably within the next few weeks. How often do you lose time.”

I told her about the fourteen gaps.

She nodded like I was telling her the weather.

“When the dreams start, do not describe them to anyone. Not out loud. Not in writing. Not even in your own head if you can help it. The more shape you give them the more real they become and the easier it is for it to hold you there.”

I asked her what “it” was.

She said “I do not know. I know it is under the building. I know it is under that corner specifically. I know it reaches you through the desk. Through the chair. Through the floor. I know it wants you asleep. I know the dreams are not dreams. They are a place. And if you go too deep into that place you do not come back the same.”

I asked her about the one-eye trick.

She almost smiled. Not quite. More like the memory of knowing how to smile.

“It works. I do not know why. But when I sleep with one eye cracked open I stay in the shallow part. I can feel it pulling but it cannot get a full grip. It needs both eyes closed. Full darkness. Full surrender. If any part of you is still watching it cannot take you under.”

I asked her if she was okay.

She looked at me with that one eye slightly wider than the other and said “I have not been okay in two years. But I am still me. That is enough.”

I am back at my desk now. It is 4pm. The light above me has flickered six times since I sat down. I counted. I have been counting everything since this morning. Minutes. Flickers. Gaps.

I do not know if I believe any of this. Part of me thinks the letter is from someone with mental health issues who fixated on a corner desk and built a mythology around coincidence. Part of me thinks fourteen gaps in my work history over five months is a lot of blank space for someone who does not remember blanking.

The woman on the fourth floor is real. Her exhaustion is real. Her advice was specific and practical in a way that does not sound like someone performing a delusion. She sounded like someone giving survival instructions because she has been surviving.

I am posting this because I want someone outside this building to know what the letter said. I want a record somewhere that is not inside these walls.

The light just flickered again. I am watching it.

I am watching everything now.
