" The fantastic postulates that there are forces in the outside world, and in our own natures, which we can neither know nor control, and these forces may even constitute the essence of our existence, beneath the comforting rational surface. The fantastic is, moreover, a product of human imagination, perhaps even an excess of imagination. It arises when laws thought to be absolute are transcended, in the borderland between life and death, the animate and the inanimate, the self and the world; it arises when the real turns into the unreal, and the solid presence into vision, dream or hallucination. The fantastic is the unexpected occurrence, the startling novelty which goes contrary to all our expectations of what is possible. The ego multiplies and splits, time and space are distorted. "
