Mysterious Shadow Emerges from Closed Elevator

Create a 30-second realistic fixed security-camera recording inside an ordinary apartment building hallway at night. IMPORTANT: This is a SINGLE CONTINUOUS STATIC CAMERA SHOT. The camera never moves, never zooms, and never changes angle. The hallway has an elevator clearly visible at the CENTER of the frame. The elevator has two clearly visible sliding doors. The man must walk directly toward the elevator doors, stop in front of them, enter the elevator through the open doors, and then the elevator doors must close. Do NOT let the man walk into a wall. Do NOT change the hallway layout. Do NOT move the elevator. Do NOT introduce any other person. VISUAL STYLE: Authentic low-quality apartment CCTV footage. Fixed ceiling-mounted security camera. Wide 16:9 frame. Slight fisheye distortion. Low-light digital noise. Mild compression artifacts. Flat fluorescent hallway lighting. Small timestamp in the corner. No cinematic camera movement. No dramatic color grading. No horror-film effects. TIMELINE: 0–7 seconds: The hallway is completely ordinary and empty. A man enters the frame from the far end and casually walks toward the elevator in the CENTER of the hallway. His normal human shadow is clearly visible on the floor beneath and behind him. 7–12 seconds: The man reaches the elevator. The elevator doors OPEN clearly. The man walks through the OPEN elevator doorway and stands INSIDE the elevator. He is completely visible inside the elevator. The elevator doors then CLOSE completely. 12–16 seconds: The hallway is empty. The closed elevator remains completely normal. The man's shadow is no longer visible because he is inside the closed elevator. Nothing happens for a few seconds. 16–20 seconds: A subtle anomaly begins. A dark human-shaped shadow slowly appears from underneath the CLOSED elevator doors. There is NO PERSON outside creating this shadow. The shadow is clearly detached from any physical person. It slowly extends farther across the hallway floor. 20–25 seconds: The detached shadow continues moving away from the elevator across the floor. It moves like the shadow of a person walking, even though there is NO PERSON anywhere in the hallway. The elevator doors remain CLOSED the entire time. The physical environment remains completely unchanged. 25–30 seconds: The detached shadow reaches the middle of the hallway. It suddenly stops. Hold on the empty hallway with the impossible shadow visible on the floor. Then abruptly CUT TO BLACK. ABSOLUTE PRIORITIES: 1. The man MUST enter the elevator, not the wall. 2. The elevator must be clearly visible and centered. 3. The elevator doors must visibly OPEN before he enters. 4. The man must be completely INSIDE the elevator before the doors close. 5. The elevator doors must remain CLOSED while the detached shadow emerges. 6. The detached shadow must visibly come from underneath the CLOSED elevator doors. 7. There must be NO PERSON outside the elevator creating the shadow. 8. Keep the camera completely stationary. 9. Do not invent additional events. The first 15 seconds should look boring and completely authentic. The supernatural event should begin only after the elevator doors have closed. The goal is: ordinary CCTV → barely noticeable anomaly → "wait, what?" → impossible detached shadow → abrupt cut. No subtitles. No narration. No music. No text explaining what happened.
