"Time will pass and you'll continue to be lost."
Dafoe's character, living as a dead man, seems lost. We watch as he searches for the unknown, for nothing perhaps, or simply just the end of the road. He aimlessly navigates through his memories, through various terrains, digging up a history of traumatic confusion which amasses into nothing in particular. Wait, I'm lost as well, what was I trying to say? It's like I'm Thinking of Ending Things if it were made from the emotive part of the brain and not the logical one.
