Self-contained photorealistic horror micro-story, one bathroom, one practical light source. Setup: a woman brushes her teeth at the mirror of a dim apartment bathroom, faucet running, fluorescent tube buzzing; mundane close-mic sound design, no music. Cut to: the turn — she stops brushing to glance at her phone — but in the mirror her reflection keeps brushing for half a second before freezing, a hair out of sync; the faucet hiss thins as a sub-bass tone creeps in, and when she leans closer and tilts her head, the reflection tilts the wrong way. Cut to: she snaps the light switch off and the room drops to blackness except the mirror, which stays lit — the reflection still standing there, toothbrush lowered, smiling; a dry violin scrape under a wet whisper of static. Final shot: the reflection slowly raises one finger to its lips, and the mirror light dies; total silence, a single heartbeat, hard cut to black on one faucet drip. Desaturated fluorescent-green grade with crushed blacks, 35mm film grain, harsh single-source volumetric light, ultra-detailed, locked-off then slow-creeping camera movement, tight micro-short pacing, no text, no captions, no watermark.
