Use the uploaded reference image as the exact main character. A young blonde woman with blue eyes and natural freckles walks alone through a dimly lit apartment hallway at night. Cinematic psychological horror, photorealistic, realistic skin and facial expressions, subtle handheld camera movement, moody warm lighting. 0–4s: Medium tracking shot as she walks down the silent hallway. Her phone suddenly vibrates. Close-up of the phone screen showing: “DON’T LOOK BEHIND YOU.” 4–8s: She stops immediately, looking nervous. Slow close-up on her face as she hears only faint hallway ambience. She slowly turns her head—the hallway is completely empty. 8–12s: Her phone vibrates again. Close-up screen: “I SAID DON’T.” She whispers, “Who is this?” 12–15s: Another vibration. Screen reads: “I’M STANDING RIGHT BEHIND YOU.” Her eyes widen in terror. Camera slowly moves behind her shoulder as if someone is approaching. CUT TO BLACK. 9:16 vertical, realistic motion, natural acting, no music, only footsteps, breathing, phone vibrations and subtle room ambience. No exaggerated CGI, no distorted face, maintain the exact same character identity throughout.
