The Hum of the Unseen

I’ve never been able to explain this properly, and I doubt I ever will. But I need to write it down, even if it’s just for myself, in the hope that putting it on paper might give me some clarity. I’m not looking for sympathy, just maybe a little understanding. If you’ve ever felt the hair on your neck stand up for no reason, or seen a flicker of movement in the corner of your eye that vanishes when you turn, then you might know something of what I’m talking about. But what I’ve experienced is more than that, and it’s been with me for as long as I can remember.

It started when I was a child, growing up in a small, isolated town surrounded by endless pine forests. I used to play in the woods behind our house, but I never liked going too deep. There was a spot where the trees seemed to close in, and the air grew still, and I could feel a low hum that wasn’t audible, but felt more like a vibration in my bones. I would stand at the edge of that clearing, and I would see them out of the corner of my eye: tall, amorphous shapes that slipped between the trunks, darker than the deepest shadow. They never came closer, but they were always there, watching.

My mother told me I had an overactive imagination, and I believed her. I tried to ignore them, but as I got older, they became harder to dismiss. They weren’t just in the woods anymore. I’d see them in my bedroom at night, standing in the corner where the light didn’t reach, or in the hallway, a blur of darkness that shifted when I blinked. They never made a sound, but I could feel their presence like a pressure against my skin. And the hum, that low, thrumming vibration, became a constant companion, a background noise that only I could hear.

By my teenage years, I had learned to live with them. I called them the Watchers, though they didn’t seem to be looking at me in a menacing way. It was more like they were just there, a part of the landscape of my life. I never told anyone, not even my closest friend, Mara, who lived next door. She was always so practical, so grounded, and I was afraid she’d think I was crazy. But one evening, as we were sitting on the porch watching the sunset, I felt a chill run down my spine, and I knew they were there, just beyond the treeline. I turned to Mara, and I saw her staring intently at the same spot, her face pale.

‘Do you see them too?’ I asked, my voice barely a whisper.

She shook her head, but her eyes didn’t move. ‘I hear something,’ she said. ‘A humming. Like a far-off generator.’

My heart raced. I wasn’t alone. I told her everything, and to my amazement, she didn’t laugh. She said she’d felt it too, that same low hum, whenever she came near our house. She called it a ‘primal warning’ and told me we needed to figure out what it was. That night, we made a pact to discover the source, to find out why we were the only ones who noticed.

We started by researching the history of our town. We discovered that the exact spot where the woods cleared was once the site of an old asylum, torn down decades ago. The records were sparse, but we found a map in the library’s archives that marked the asylum’s boundaries, and our neighborhood was built directly on its former grounds. The asylum had a reputation for ‘unorthodox’ treatments, and many patients died under mysterious circumstances. The deeper we dug, the more unsettled we became. We found references to a machine that was used to ‘realign spiritual energies,’ whatever that meant. It was supposedly destroyed, but we couldn’t find any proof of its disposal.

One afternoon, we gathered our courage and ventured into the woods, following the hum. It grew stronger as we approached the clearing, and in the center, we found a patch of earth that was unnaturally smooth, as if something had been removed and the ground had healed over. The hum was loudest there, and I could feel the Watchers pressing closer than ever before. They were no longer just watching; they were converging, forming a loose circle around us, their shapes rippling like heat mirages. I could feel a pull, as if the ground itself was trying to draw us in.

Mara knelt down and pressed her hands to the soil. She gasped and recoiled. ‘They’re still here,’ she said. ‘Buried. The machine is still here, and it’s still on.’

That was the last thing she said before the ground gave way beneath her. I tried to grab her, but I was too slow. She fell into a hole that seemed to have no bottom, and her scream echoed in the darkness. I called her name, but there was no response. I was frozen, staring into the pit, when the Watchers began to move. They flowed into the hole, dozens of them, like ink draining into water, until they were all gone, and the ground sealed itself back up, as if nothing had happened.

I ran back to town, sobbing, and told the authorities that Mara had fallen into a sinkhole. They searched for days but found nothing. They assumed she had run away, or worse. I knew the truth, but I couldn’t tell anyone. Who would believe me?

That was six years ago. I’ve moved away, but the hum never left me. It’s a constant companion now, a reminder that I’m not alone and never will be. I still see the Watchers, but they’re not in the shadows anymore. They’re always there, just at the edge of my vision, and sometimes, when I look in the mirror, I catch a glimpse of a darker shape behind me, and I know that they’re waiting.

I don’t know if they’re ghosts, or something else entirely. I don’t know if they’re malevolent or just lost. But I know that I cannot escape them, and I’ve come to accept that I never will. Perhaps the hum is not a warning, but a call, and one day, I will answer it. Until then, I will keep writing, keep trying to understand, and I will hold on to the fragile hope that somewhere out there, someone else understands what it’s like to hear the hum of the unseen.
