Everything that exists hums with a frequency.
Every wall, every body, every thought.
Vibrations hold reality together, like threads pulled tight across an endless loom.
Most people live their entire lives without noticing the hum. They dismiss it as the buzz of a lightbulb, the ringing in their ears, or the faint echo inside an empty room. But it's always there, beneath everything.
When emotions swell too strongly—rage, grief, love, despair—the frequency wavers. The threads loosen. And in rare, terrible moments, a door opens.
No one builds these doors. They are not marked, not locked, not safe. They lead away from the steady pitch of our world and into others where the hum is wrong. Louder. Colder. Hungrier.
Those who step through don't always know they've crossed. Some think they're lost. Some think they're dreaming. Some believe they're still home.
But the walls know. The lights know.
And once the frequency has changed, it never forgets who tuned in.
