Create a highly realistic cinematic horror sequence set inside a quiet apartment building late at night. A young woman enters an empty elevator alone, wearing simple casual clothes, with natural realistic facial features and subtle nervous expressions. The elevator moves strangely, stopping at several floors. Every time the doors open, the exact same long, empty apartment corridor appears outside, dimly lit by flickering ceiling lights. She becomes increasingly confused and frightened, repeatedly pressing the elevator buttons and looking down the corridor. On the final stop, the elevator doors slowly slide open. At the far end of the corridor stands another young woman who looks exactly identical to her, motionless and staring directly at her. The atmosphere becomes completely silent. The woman inside the elevator slowly steps forward, unable to understand what she is seeing. The identical woman suddenly tilts her head at an unnatural angle and takes one slow step toward her. Without warning, the corridor woman violently charges toward her with extremely fast, unnatural movement. The original woman screams and tries to retreat into the elevator, but the other woman tackles her and both fall to the floor. The corridor woman grabs her and aggressively drags her backward across the floor while the original woman desperately tries to hold onto the elevator doorway. The elevator lights flicker rapidly, casting harsh moving shadows across both faces. The original woman manages to reach one hand toward the elevator control panel, desperately trying to press the door-close button. The corridor woman suddenly grabs her wrist and pulls her away. The elevator doors begin closing by themselves, slowly separating the two women. The original woman reaches toward the narrowing gap in panic while the identical woman stares at her with an eerie, emotionless expression. The doors finally slam shut. Cut to a completely empty corridor. No one is visible. A smartphone lies on the floor where the struggle happened, its screen still glowing and displaying 2:13 AM. The hallway lights flicker once, then everything goes completely dark.
