Retrogenesis is a theory that suggests that the brain of a person with Alzheimer's disease deteriorates in the reverse order that the brain developed from birth. Through this experiments on four elements creating a We, a part of the We is trying to understand how Brain works as a link and a parasite, while retrogenesis is occurring. You (a reader) approaches the page (labyrinth) and in the experiences depicted which could or could not be electrical impulses created by Brain, but without any reality to sustain them, try to figure out the story.
