From a tale one expects a bit of wildness, of exaggeration and dramatic effect. The tale has no inherent concern with decorum, balance or harmony... A tale may not display a great deal of structural, psychological, or narrative sophistication, though it might possess all three, but it seldom takes its eye off its primary goal, the creation of a particular emotional state in its reader. Depending on the tale, that state could be wonder, amazement, shock, terror, anger, anxiety, melancholia, or the momentary frisson of horror.
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.
It is as though some old part of yourself wakes up in you, terrified, useless in the life you have, its skills and habits destructive but intact, and what is left of the present you, the person you have become, wilts and shrivels in sadness or despair: the person you have become is only a thin shell over this other, more electric and endangered self. The strongest, the least digested parts of your experience can rise up and put you back where you were when they occurred; all the rest of you stands back and weeps.
