## Synopsis (in-house rewrite)

Night again in the apartment. A humidifier’s low whir.

A husband’s sleep-talk curdles into something wet and wrong. Clinic visits leave the wife empty-handed. By the time the shaman’s candle gutters, the bedframe shakes like an animal inside it.

One more flicker, then the light goes out.

**Mood tags**: body-horror, dread, slow-burn
