It was just a dream.

A man with dark hair, wearing a dark jacket, is shown in a dimly lit room with green walls, then running along the edge of a skyscraper rooftop, falling through the air with his arms outstretched, and finally seen from above, falling between two towering buildings. The sequence loops, showing the man's descent from a high vantage point, beginning with a close-up of his face, followed by his run, fall, and the final view of him plummeting between the buildings.
