Karaoke Night Shatters When a Singer's Head Tilts and She Attacks

15s realistic Korean noraebang horror: Woman sings happily with friends under disco lights; voice glitches, karaoke screen freezes, lights strobe, head tilts unnaturally. She stops blinking, grips mic tightly, then screams an inhuman distorted note. Jaw drops unnaturally, eyes reflect wrong; friends panic. She lunges across the table, knocking drinks/tambourine over. Friend strikes her with tambourine; she staggers into mic stand. They flee through the door into a flickering neon hallway. She follows slowly, head tilted, silhouetted behind them. Group freezes at the far end as she approaches; cut to black. Handheld camera, escalating tension, motion blur, chaotic strobe lighting, cinematic realistic body horror.
