Create a video starting with the generated image, showing the subject continuously running down the hallway. The video should have a single continuous shot without cuts, focusing on the subject's terrified face with visible bloodstains. The camera should follow the character dynamically, with intense shaking to mimic a handheld perspective while moving at high speed. The hallway walls and ceiling should feature black, tentacle-like entities that quickly spread toward the subject. As the tentacles approach rapidly, the subject turns around and screams in terror before the scene abruptly flashes to pure white exposure, completely covering the frame. The final video should include sound effects like abrupt interruptions or screams. The setting is a dirty, abandoned hospital hallway with clear details, and the subject's face and limbs should remain intact and consistent throughout.
