As the man struggles to collect his memories, he finds himself getting lost in the labyrinth of his disordered mind. 

Labyrinth (From “The Book of Symbols”):

The essentially dual, paradoxical nature of the labyrinth is both circular and linear, simple and complex, historical and temporal. Contained within a compact space, a long and difficult path constantly doubles back on itself, leading circuitously to a mysterious and invisible center. From within, the view is extremely restricted and confusing, while from above one discovers a supreme artistry and order.
