No one wants to argue that "a kind of parallel dimension" could very well be a dream world? Remember, I can claim this just as easily as some one else can claim that meant "mirror world".

Has there been an official translation of HH? I wasn't aware there had been. Translation are hardly always perfect re-interpretations of what was actually said. And, to me, "another dimension" is far too vague to be a counter to the theory that it's a dream.

"A kind of parallel world".
