Oblivion

A girl
After an accident with an old man, at a crossroads of whether to stay or run away,
goes back an hour and picks up the old man on the way ((the spirit of the same old man))
And on the way, the old man disappears after getting off.
A little further on, she sees the same old man in the same position of running away after the accident. She gets off and sees that the same old man is dead. He crashes into a car. She wakes up from the dream. The old man with a scarred face knocks on the window.
