Mirror Glitch Horror

[Style] Vlog style, hyper-realism, fixed camera angles for a realistic feel, natural lighting, with a touch of suspense and thriller elements. 
[Duration] 15 seconds 
[Main Character (Remember to send reference image)] A sexy young woman is preparing to wash up and sleep in front of her bathroom sink. 
[00:00-00:06] Shot 1: Normalcy of everyday life. Scene: In a regular bathroom with a large mirror. Action: The protagonist is brushing his teeth in front of a mirror, foaming at his mouth. She brushed her teeth while making all sorts of funny faces (winking and winking) in front of the mirror. Key detail: At this moment, the reflection in the mirror is completely normal, and the movements are synchronized. 
[00:06-00:11] Scene 2: A bug appears (The Glitch). Action: After brushing his teeth, the protagonist lowers his head to blow out the foam, then turns to leave the bathroom. High-Energy Moment (Core Highlight): Just as the protagonist's true body has turned away from the mirror, the "reflection" in the mirror surprisingly remains unmoved! That "reflection" still maintained its toothbrushing posture, even smirking mischievously and raising an eyebrow at the camera, pausing for a full two seconds before suddenly frantically "flashing" and chasing the main body, disappearing. Director's note: The goal is to create an extremely realistic sense of "network latency," with reflections that convey a sense of independent consciousness. 
[00:11-00:15] Shot 3: The Punchline. Action: The protagonist, who has already reached the door, seems to sense something is wrong and suddenly turns to look in the mirror. The result: the mirror had now fully returned to normal, empty, only reflecting the wall opposite. The protagonist looked confused and terrified, glanced around the room, and showed a horrified expression. The scene freezes on the protagonist's stunned face (horror movie effect).
