A montage sequence showing Tony Stark from the movie Iron Man, looking disoriented, traumatized, and exhausted immediately after being held captive by terrorists and having an arc reactor implanted in his chest.
This video is used to depict feelings of deep confusion, the moment reality hits after a chaotic event, dissociation, or the overwhelming realization of a bad situation.
