Possessed Hospital Horror Scene

the prompt

A dim hospital room at night, lit only by the pale blue glow of medical monitors and a flickering fluorescent light in the hallway beyond a half-open door. A frail woman lies in a hospital bed, tubes and wires connected to her arms, an oxygen mask over her face. Her chest rises weakly. Camera opens on a slow, creeping dolly-in toward her face, heart monitor beeping steadily.

Suddenly, the beeping accelerates, then flatlines. Her eyes snap open — pupils fully black. Her back arches unnaturally, lifting off the mattress as if pulled by an invisible force. The monitors spark and glitch, screens flickering with static. Shadows in the room seem to thicken and crawl along the walls, converging toward her.

Her hands claw at the bed rails, fingers bending backward at wrong angles. A guttural, layered voice (not her own) escapes her throat as her head snaps toward the camera in a sharp, jerking motion. The ceiling lights burst one by one in a rolling wave down the hallway outside. Wind with no source rustles the curtains violently.

Extreme close-up: her irises turn milky white, veins darkening rapidly beneath her skin like ink spreading through water. She lets out a piercing scream that distorts into something inhuman. Cut to black as the last monitor explodes in sparks.
