As Arthur and Ariadne ascend a square staircase, they paradoxically find themselves returning to the lower level they had seemingly left behind. The sequence serves as a flawless, live-action realization of an M.C. Escher optical illusion, capturing the dizzying impossibility of ascending only to emerge from below.
Within the film’s lexicon, this phenomenon is termed “paradoxical architecture.” Operating under the premise that the dream realm can entirely circumvent the laws of classical physics, the narrative posits that a structure designed to simulate continuity from a specific vantage point will, in fact, become physically operational within the architecture of the mind.
