Soaked woman floating through eerie night train carriage

(Low-angle, worm's-eye view), cinematic horror scene: a woman with long black hair, wearing a long white nightgown—her hair and clothes completely soaked—floats as she walks through an old train carriage on a full-moon night. All the passengers sit silently in their seats, engrossed in their mobile phones, with no one noticing the soaked woman floating past.
