- Dr. Robert Banger: When the pressures of modern society become too great for a person, when one's chemical dynamic becomes such that they are unbalanced, that they cease painting within the lines, they come to us. These are the people that society would prefer just go away -- the shadow people. The shadow people that project upon us their shadow and remind us just how tenuous mental health is. Our worst fears. They remind us how easy it can be to slip.
