Door opens, horror version

The prompt

Medium shot of a young boy lying in bed in a dark bedroom at night, the blanket pulled to his chin, photoreal horror, locked camera. 0–2s: only faint cold moonlight from the window on his face. 2–4s: the bedroom door creaks open out of frame. 4–6s: a bright wedge of cold blue-white hallway light sweeps across the floor and climbs up the bed onto his face, with the tall, thin shadow of a figure stretched across it. 6–8s: the boy lies frozen in the band of cold light, eyes wide, staring toward the doorway. Throughout: toys in the shadows, hard cold light after the door opens, fixed camera, one continuous take.
