Eerie Silhouette Haunts Glossy Hospital Corridor in Photorealistic Horror

Create a 15-second photorealistic cinematic horror sequence set inside a dim, deserted hospital corridor at night. Begin with a slow forward tracking shot through a long empty hallway with glossy reflective floors, cold fluorescent ceiling lights, closed patient-room doors, metal handrails, and an abandoned wheelchair. A frightened middle-aged woman suddenly appears at the far end of the corridor, cautiously walking and looking over her shoulder → camera follows as she senses something behind her → cut to an intense extreme close-up of her terrified eyes and trembling face → return to the hallway where an eerie dark human silhouette slowly emerges in the distance → the woman turns toward the camera in panic → final shot returns to the completely empty corridor as the silhouette mysteriously disappears. Slow suspenseful camera movement transitioning into subtle handheld shake, realistic motion blur, shallow depth of field, cold desaturated hospital lighting, natural skin texture, wet reflective floor, atmospheric darkness, realistic facial expressions and believable human movement. Psychological horror atmosphere, grounded photorealistic cinematography, unsettling silence and tension. No animation, cartoon look, subtitles, logos, watermark, or exaggerated CGI.
