I have a stack of books I'm getting through, including some Morrison Batman, but clear one thing up for me, someone--is Morrison saying all those weird adventures actually occurred in Bruce's continuity, or are some of them hallucinations? Did Bruce at some point encounter the rainbow creature? Zurr En Arrh (spelling, I know) had to have been a hallucination, for example, a fictional world Bruce made for that personality, or was it (I just don't see many of those adventures making it into current continuity as actual happenings, but hey, I could be wrong).
