The study was a narrow room at the back of the house, lined with shelves of forgotten textbooks and a single window that faced the gravel driveway. My desk sat against the far wall, the old computer monitor humming like a trapped fly. It was a relic, its CRT screen glowing a sickly green, and the desk lamp beside it cast a weak, yellow cone that barely reached the keyboard. My cat, a grey tabby named Miso, perched on the armchair behind me, her eyes tracking the occasional sweep of headlights across the ceiling as cars turned off the main road. The house was silent except for the hum of the computer and the distant, rhythmic creak of the water heater in the basement.
I was chatting with a friend about some trivial nonsense, my chair creaking as I leaned back and forth, watching my own elongated shadow dance across the wall opposite the window. The shadow was a familiar companion—it stretched and shrank with my movements, sometimes splitting into two when the car lights hit just right. But tonight, as I tilted back and forth, I noticed something odd: my shadow seemed to lag behind my movements, like it was moving through water. I froze, and the shadow snapped back into alignment, but a cold knot tightened in my stomach. I told myself it was just the flickering lamp, a trick of the eyes.
I turned back to the keyboard, typing a half-hearted response, when Miso let out a low growl. I swiveled around to look at her—she was staring at the shadow on the wall, her fur bristled. The shadow was not mine anymore. It was upright, unmoving, a perfect silhouette of a person standing between me and the window, but I was not standing. I was sitting. The shadow had no corresponding body. I blinked, and it was gone, but Miso’s eyes remained fixed on the spot, her ears flattened.
I tried to laugh it off, telling myself that the shadow of the chair’s backrest had fooled me. But Miso would not relax; she kept staring at the wall, and then her gaze shifted to the window. I followed her eyes. Through the window, beyond the driveway, the streetlight cast a pool of orange light on the gravel, and something was standing at the edge of that light—a figure, dark and featureless, as if cut from the same shadow that had been on the wall. It was too far to make out details, but I felt its attention boring into me, into the room.
I reached for the lamp switch, but my hand paused. The moment I turned off the light, the room would be black except for the monitor’s glow, and the window would become a mirror, reflecting everything behind me. I didn’t want to see what might be reflected. But the figure outside did not move. It just stood there, patient, like it was waiting for me to do something. I forced myself to look away, back to the computer, and my fingers trembled on the keyboard. I typed to my friend, “I think someone’s outside my window.” The reply came: “What? Call the cops.” I didn’t want to call the cops. I couldn’t explain the shadow.
I turned back to the window, and the figure was gone. But Miso was now on the floor, backing away from the door, her back arched. I heard a sound from the hallway—a soft scraping, like something being dragged across the carpet. My brother’s snoring had stopped. The water heater had gone silent. The only sound was the hum of the computer, which suddenly seemed louder, and the scratch of my own breath. I swiveled my chair toward the door, ready to lock it, but the door was already closed. I had left it open a crack. Now it was shut.
The shadow on the wall detached itself. It slid off the wall and onto the floor, pooling like ink, and began to crawl toward the door. I watched it, paralyzed, as it slipped under the door and into the hallway. A moment later, I heard my brother’s voice, but it was not his voice. It was layered, like it was being said over a bad recording, and it came from right outside my door: “I’m coming in.”
I grabbed the desk lamp, yanking its cord from the wall, and held it like a weapon. The room went dark, and the window became a pitch-black mirror. In that mirror, I saw my own face—pale, eyes wide—and behind me, a tall, slender shape with no features, its head tilted as if curious. The shape reached out a hand of pure shadow, and I felt a cold pressure on my shoulder, like a glove filled with ice water. I screamed, and the shape retracted.
The lamp bulb flickered on its own, casting a weak light. I looked around the room. The shadow was gone. The door was open a crack again. Miso was on the armchair, grooming herself, as if nothing had happened. I heard my brother’s snoring resume, the water heater kick on with a groan. I sat in the chair, shaking, staring at the window. The streetlight was off now, and the world outside was black. I didn’t sleep that night. I kept the lamp on and watched the wall, waiting for the shadow to return. It didn’t, but I knew it was only a matter of time.
Weeks later, I learned that the house’s previous owner had died in that room, sitting in front of a computer, alone. The police report mentioned that the man’s neighbor had seen a figure standing in the window the night he died, but by the time the police arrived, the figure was gone. I never told anyone what I saw. But sometimes, late at night, I still see a shadow in the corner of my eye, and I remember the way that shape moved, as if it were not bound by the laws of light. I don’t turn off the lamp anymore. I don’t want to see what else lives in the dark.
That was years ago. I sold the house and moved to the city. But last week, I was on a video call with a friend, and in the reflection of the window behind me, I saw a dark shape in the corner of my room. It was gone in an instant, but it was there. I think it followed me. And now, as I write this, I’m sitting in a well-lit room, and I’ve just noticed that my shadow is not matching my movements. It’s been lagging behind by half a second. I’m going to look at the wall now, and I’m begging you—pray that I see my own shadow, and not something else wearing its shape.
