Human beings across every culture I know about require such stories, stories with cool winds and wood smoke. They speak to something deep within us, the capacity to conceptualize, objectify and find patterns, thereby to create the flow of events and perceptions that find perfect expression in fiction. We are built this way, we create stories by reflex, unstoppably. But this elegant system really works best when the elements of the emerging story, whether is is being written or being read, are taken as literal fact. Almost always, to respond to the particulars of the fantastic as if they were metaphorical or allegorical is to drain them of vitality.
