深夜ジムのサスペンス

英語プロンプト

Person from Image1; facial features and hairstyle must match exactly. Ignore the reference outfit, background, pose, and text. She wears a black gym tank top, dark workout leggings, and looks naturally sweaty after training. 9:16 vertical format. 30-second late-night gym psychological horror / found-footage sequence: Ultra-realistic old iPhone 1x standard lens, raw low-quality phone footage, heavy compression and constant digital noise, harsh cool-green fluorescent gym lighting, natural exposure, no cinematic grading. The gym is almost completely empty late at night. Realistic ambient gym sounds, distant machine hum, footsteps, breathing and room echo. 0–6s — Weight training: She is alone in the nearly empty gym doing heavy weightlifting. She performs controlled dumbbell curls and then a heavy shoulder press, visibly struggling and breathing heavily. Sweat builds naturally on her face and arms. She finishes the set, puts the weights down, catches her breath, grabs her phone and heads toward the bathroom. 6–10s — Entering bathroom: She enters the empty gym bathroom, places her phone near the sink, looks exhausted, drinks water and splashes cold water onto her face. She wipes her face and looks into the mirror while recovering. 10–14s — Something appears: While staring at her reflection, a strange dark human-like monster silhouette suddenly appears faintly behind her in the mirror. She doesn't notice it immediately. She looks down, takes a breath, then slowly looks back at the mirror. 14–18s — Fear: The shadowy figure is now noticeably closer behind her. She suddenly notices it and freezes. Her breathing becomes faster. She slowly turns around, but there is nothing behind her. She looks back at the mirror and the creature is still there, even closer. 18–22s — Escape: She gasps in genuine fear, grabs her phone and immediately runs out of the bathroom. Her footsteps echo through the empty gym corridor. She keeps looking behind her while running. 22–26s — Back into the gym: She rushes back into the main gym area, visibly panicked. She quickly looks around the empty gym, then spots her gym bag where she left it. She runs toward it, grabs the bag and hurriedly puts the strap over her shoulder. 26–30s — Final escape: Without stopping, she runs toward the gym exit with her bag. She pushes through the doors and escapes outside. Just before leaving, she briefly looks back toward the dark gym interior. Nothing is visible. She quickly turns and runs away. Freeze mid-run as the footage ends. Maintain realistic skin pores, sweat, flushed skin, damp hair, natural body movement and authentic fear. The monster should be subtle, dark and unsettling rather than an exaggerated CGI creature. Keep the entire sequence visually consistent with raw old-iPhone footage. Audio: Heavy breathing, weights hitting the floor, gym equipment sounds, footsteps, water splashing, bathroom echo, phone handling sounds, door opening, distant nighttime ambience. No music. Negative: No BGM, no dialogue, no text, no readable signage, no beauty filter, no cinematic color grading, no fisheye, no distortion, no vignette, no jump cuts, no scene skipping, no time compression, no exaggerated CGI monster, no gore.
