Quite worryingly, I also had a couple 7th guest themed dreams last month and for some reason they're remained in my head very vividly. Rest assured they were not knightmares though (not a microscope puzzle in sight).
Of course, a microscope puzzle was out of question (although that, indeed, would have been a nightmare). I suppose you had themed dreams with the chess puzzles, as it was a Knightmare.
Ok, bad joke, but I couldn't resist
