It's clear in Dostoevsky. The writer's task to inhabit that mysterious blank space of the collective subconscious. To inhabit, and through that, find the dreams and myths that occur spontaneously, the collective of good mental health. One has to go through that territory, of the common experiences, the dreamer's dreams, the not-wanting-to-get-up-out-of-bed, the Monday morning, of the common things of heartbreak, to find the right perspective to find the myths of good health, of finding the true person within to base a life upon. The territory, the tale, it has its ultimate purpose, its way of sorting things out.
Perhaps it is not the point, as much, the events of the laboratory, but the myths themselves. The laboratory must be shown, dramatized, to show the fullness of the myth, its iceberg depths, but it's the result that are important. The Christian myth has that succinctness.
