I was twelve, and my dad had just taken me to my first big concert: a doom metal band called Grieving Earth. The sound had rattled my bones, and the lights had burned strange afterimages into my eyes. We got home around midnight, and I crawled into bed, still buzzing, my ears humming with a low, persistent drone.
I lay there, staring at the ceiling fan, counting the rotations to slow my racing mind. Around one in the morning, a sound cut through the hum. It was faint, tinny, like music from a distant radio. I recognized the riff: ‘Flying High Again’ by Black Sabbath. I froze. My old MP3 player was on my nightstand, but I’d turned it off that morning. I was sure of it.
I told myself it was just my imagination, a trick of exhaustion. But the music continued, growing slightly louder, as if someone were turning up the volume from inside the device. The song ended, and I heard a crackle, then a voice—low, garbled, like a man speaking underwater. I couldn’t make out the words, but the tone made my stomach clench.
At 2:15, a new sound joined: a rhythmic thumping from my brother’s room across the hall. He was thirteen, a fan of punk and industrial noise. I thought he might be tapping his foot to a song, but the beat was wrong—irregular, like a heart struggling. Then came a mechanical grinding, the sound of gears turning against each other, and beneath it, a low groan that seemed to vibrate through the walls.
The sounds merged into a dissonant symphony: the ghost of the concert’s bass, the thump of something heavy, the screech of metal on metal, and a human-like growl that made my hair stand on end. I pulled the covers over my head, my heart pounding so hard I could feel it in my throat.
By 3:10, my bladder was screaming. The hallway to the bathroom was dark, and I knew I couldn’t hold it any longer. I crept out of bed, my feet cold on the wooden floor. As I passed my brother’s door, the sounds stopped. Dead quiet. I felt a presence, a pressure in the air, like being watched.
I reached the bathroom, flicked on the light, and did my business as fast as I could. As I washed my hands, I glanced in the mirror. Behind me, the shower curtain was drawn. I didn’t remember pulling it. The fabric rippled, as if something had brushed against it.
I backed away, my hand on the doorknob, when I heard a whisper, intimate and close, right by my ear: ‘We know you hear it.’
I bolted back to my room, slammed the door, and jumped under the covers. I tried to convince myself it was a dream, but the cold sweat on my skin said otherwise.
I must have dozed off, because I woke to gray light filtering through the curtains. My MP3 player was on the floor, shattered, as if it had been thrown. My brother was in the doorway, his face pale and drawn. He looked at me, and his lips moved, but no sound came out. Then he raised a hand, pointing at the window.
I turned. On the glass, in a condensation that hadn’t been there before, was a symbol: a circle with a jagged antler branching upward, drawn in a substance that looked like dried blood. I don’t know what it meant, but I knew it was a warning. We never spoke of that night, and we moved out a month later. But sometimes, in the quiet, I still hear that low, relentless drone, and I know it found us again. Some frequencies are not meant to be heard, and some concerts open doors you can never close.
