This movie is interesting in its use of corridors. The more obvious use of corridors can be seen in the police inspectors recurring nightmare, he is trapped in the long hallway, the distance to his goal is too great and he is never able to catch the assailant that he chases, the walls too quickly cave in and the floor becomes liquid.

Another important use of corridors seen in this movie is provided by the buildings of the street as they confine the dream parade which continues on in an endless stream towards a future destination. That destination ends up being the physical reality of the characters. As the line between reality and the surreal is blurred, the main character Shiba is able to stray from the path of the parade to find a more sinister world hidden behind the illusion of the corridor walls.
