Spooky Hallway CCTV Security Footage

Create a 30-second ultra-realistic fixed CCTV security-camera recording inside an ordinary apartment building hallway at night. The entire video must be ONE CONTINUOUS STATIC SHOT from a ceiling-mounted security camera. The camera NEVER moves. No cuts. No camera shake. No zoom. No change of perspective. The hallway is completely ordinary: beige walls, apartment doors, tiled floor, fluorescent ceiling lights. A single adult man wearing ordinary casual clothes walks slowly through the hallway. His shadow is clearly visible on the floor. IMPORTANT: Keep the man's body, clothing, face, shadow, hallway geometry, lighting and camera position CONSISTENT throughout the entire video. TIMELINE: 0–10 seconds: The hallway is empty. The man enters the frame and casually walks down the hallway. Everything looks completely normal. 10–15 seconds: The man stops underneath one of the ceiling lights. He stands still for a moment. His shadow is directly beneath and behind him, behaving normally. 15–19 seconds: The man begins walking forward again. His body moves normally. BUT HIS SHADOW DOES NOT MOVE. The man's shadow remains exactly where it was when he stopped. The man continues walking several steps away from it. The shadow stays completely stationary on the floor. 19–23 seconds: The man suddenly notices something is wrong. He stops walking. He slowly turns his head and looks back toward his shadow. The shadow remains in the exact location where he originally stopped. 23–27 seconds: The man remains completely still. His shadow slowly turns its head toward him. IMPORTANT: Only the SHADOW moves. The man's actual body does NOT move. The shadow's movement must be subtle, slow and physically impossible. 27–30 seconds: The man takes one small step backward. The shadow takes one small step FORWARD toward him. The man freezes. Abruptly CUT TO BLACK. REALISM IS MORE IMPORTANT THAN DRAMA. The footage must initially look like completely authentic boring apartment CCTV. Use realistic low-quality surveillance footage: 16:9 aspect ratio, fixed wide-angle security camera, mild compression, low-light digital noise, subtle fluorescent lighting, realistic shadows and ordinary colors. DO NOT use: glowing shadows, black smoke, ghost effects, distorted humans, monsters, floating objects, melting, morphing, extra people, changing architecture, camera movement, cinematic lighting, dramatic effects, or exaggerated horror imagery. The supernatural effect must come ONLY from the shadow behaving independently of the person.
