I live in Apartment 4B. I am a man of habits—tea at 7 AM, the Times at 8, and the observation of my neighbors from 9 to 5. My name is Leo, and I am the only person in this building who knows that the world is becoming a photograph.

It started with Clara in 4C. Clara is a physicist, a woman who carries the weight of the universe in her tired eyes. Six months ago, she stopped coming out for her morning coffee. When she did appear, she looked as if she were being viewed through a frosted pane of glass.

I began to keep a log.

*Day 12:* Clara was seen shouting at a mailbox. She kept saying, "It's flattening! Can't you feel the depth disappearing?" The mailman thought she was having a breakdown. I noticed that the mailbox seemed slightly thinner than it was yesterday.

*Day 45:* Clara tried to warn the building manager. She brought a series of diagrams—complex, swirling shapes that looked like crushed stars. She told him that a "Dimensional Collapse" was sweeping through the city, and that we were all being pressed into a two-dimensional plane. The manager told her to keep the noise down. I noticed that the hallway carpet felt strangely smooth, as if the fibers had been pressed flat.

*Day 89:* Clara stopped speaking. She spent her days standing in the center of her living room, arms outstretched, as if trying to hold up the ceiling. I watched her through the gap in our doors. She looked terrified, but there was a strange, serene acceptance in her eyes. She knew the exact moment the collapse would reach us.

I didn't believe her at first. I am a librarian; I believe in facts, in ink, in the solid weight of a book. But then, I saw the bird. A pigeon landed on my windowsill, and as it turned, it momentarily vanished. For a split second, it was a perfect, flat silhouette against the brick wall, a paper cutout of a bird.

Then it snapped back.

The dread began to seep into my bones. I started observing the others. Mr. Henderson in 3A began to walk with a strange, sliding motion, as if he were gliding on ice. The colors of the building began to shift—the reds became too bright, the shadows too sharp. The world was losing its volume, becoming a series of high-contrast images.

Last night, I heard a sound from 4C. Not a scream, but a sigh. A long, exhaling sound that seemed to echo from a great distance.

I rushed to her door and pushed it open.

Clara was gone. In her place, on the hardwood floor, was a painting. It was a breathtakingly detailed image of Clara, captured in a moment of absolute peace, her arms still outstretched. She was a masterpiece of line and color, a perfect two-dimensional representation of a human soul.

I stepped back, and as I did, I felt a sudden, sharp pinch in my chest. I looked down at my hand.

My fingers were merging. The depth of my skin was vanishing. I could see my bones, my veins, and my heart, all laid out on a single, flat surface.

I walked back to my room and opened my log. I picked up my pen, but the pen was now just a line of black ink on the page. I tried to write "Help," but the letters were already flat.

I lay down on the floor and waited. As the world around me collapsed into a final, brilliant flash of color, I realized that Clara was right. We weren't dying; we were just becoming a more efficient version of the truth.

I closed my eyes, and for the first time in my life, I felt perfectly, beautifully thin.
