[William Butler] Yeats has the phrase Hodos Chameliontos, chameleon-like, in that you don't know where the beginning or the middle or the end is, so it's an unrelieved hallucination, because you don't know where you're coming in and you don't know where you're going out. It ends, you're going into the hallucination, or maybe coming out of it, I don't know.
