If you envolve Q there can be any universe that he wishes to put you in.
I also think there are other possibilities as well. For instance, I can't remember the name of the episode in TNG, but Worf kept switching universes (each had a different outcome from the episode we had watched - Riker was in command of the Ent after stopping the Borg, but losing Picard/Locutus; Riker was in command of one of the last Starships because the Borg had taken over the entire quadrant, etc.). Given this "parallel universe" idea, it is entirely possible that the Mirror Universe is alive and well. As a famous Vulcan once said - "There are always possibilities."
