Sleep sounds for insomnia.
Insomnia has a cruel mechanic: the harder you chase sleep, the further it walks. The body is tired; the mind won't clock out. It runs the tomorrow list, replays the conversation, counts how long you've been awake — and every one of those thoughts needs quiet to be heard in. Silence, in the small hours, is the loudest thing in the house.
That's what sound is for. A steady bed of noise gives a running mind something to settle on that asks nothing back — no words, no story, nothing next. The thoughts don't stop so much as lose the room: under dark rain, a worry is one more drop in a downpour, and a drop has no scale to it. It's the same trick the fan already knows how to do, tuned for the job.
Dark rain is the sound for it — low, heavy, unchanging, the rain you hear from under a roof rather than out in it. It covers the small sounds that keep snagging a half-awake brain, and it never asks you to follow anything. You can listen to it the way you'd watch a fire: without effort.
So give the night the boring conditions it wants. Dark room, cool air, phone out of reach. Press play above, stop managing the hour, and let the rain carry the shift from awake to asleep — most people miss the exact moment it happens.
It's playing above, one tap away. Steady to the last minute, and it ends on its own.
