The story: A shadow reveals its form from the darkness underground. It communicates with a woman's consciousness, and she begins to see fragmentary memories that transcend time and place, as if daydreaming. The shadow takes on the woman's form and travels. Situating itself in places invisible from above ground, it traces what once happened there, listening to the human memories buried in the flow of time.
