The old, completely exhausted wethered conductor on the moving, crowded classic train wipes the sweat from his face and speaks directly into the camera in a deep, urgent voice: "Last night I had a dream. I was walking in a garden. There was a cherry tree. The tree was in bloom, but the blossoms were falling off. What could the dream mean?" Then the train slams on the brakes and the passengers behind him begin to scream hysterically as the camera zooms out.
