Earworm

 It started as a minor nuisance, a snippet of a nursery rhyme I hadn’t heard since I was four—something about a silver bell and a dark, damp well. At first, it was just the rhythm, a jaunty, discordant little loop that tapped against the inside of my skull.

I tried to ignore it. I focused on my work, but the silence between my keystrokes felt heavy, pregnant with that phantom melody.

**The brain is a stubborn machine.** It is designed to learn, to archive, to complete. By the third day, the "cognitive itch" became an obsession. I tried to suppress it by listening to heavy metal, by reciting technical manuals, by screaming into my pillow. But the moment the external noise stopped, the melody surged back, louder, sharper, more insistent.

By the end of the week, the loop began to change. The melodic structure—that simple, repetitive arc—started to twist. It wasn't just a song anymore; it was a rhythmic pulse that synched with my heartbeat.

I couldn’t sleep. Every time I drifted off, the loop would snap me awake, not with music, but with a sound I couldn't quite identify—a wet, clicking noise buried beneath the melody.

I went to a specialist, a neurologist who spoke in calm, clinical tones about "auditory cortex loops" and "involuntary musical imagery." He prescribed silence and white noise. He told me it would pass.

He didn't notice that while he spoke, his fingers were tapping the exact, rhythmic pulse of the song against his mahogany desk.

### The Auditory Invasion

That was the night the lyrics arrived. They weren't from the original rhyme. They were new, whispered in a voice that sounded like my own, but deeper, thinner, as if spoken through rusted wire.

*“Complete the loop,”* the voice sang, perfectly in time with the tapping of my pulse. *“Complete the loop, and you shall hear the rest.”*

I stopped eating. I stopped speaking. I sat in my darkened apartment, clutching my head, terrified that if I let my brain finish the phrase, if I finally gave in to the "replay" mechanism my own mind was forcing upon me, something would break.

The silence wasn't empty anymore. It was thick with the song. It was in the hum of the refrigerator, the drip of the faucet, the very electrical current in the walls. They were all playing it.

It is 3:00 AM. I am sitting at my desk, pen in hand. My brain is screaming, demanding the final note, the resolution of the musical phrase that has haunted me for fourteen days. The "cognitive itch" has become a physical sensation—a feeling of something burrowing deep into my auditory canal, cold and damp.

The song is no longer in my head. It is vibrating in the marrow of my bones.

I understand now. The brain isn’t just replaying a memory. It’s a receiver. It has been tuning itself, refining the pitch, strengthening the signal, waiting for me to be broken enough to let it in.

I am going to finish the song now. I have to. The tapping in my head has stopped, and in its place, I hear something standing behind me. It is breathing in the exact tempo of the chorus.

It has been waiting for the final note. It has been waiting for me to open the door.
