In that S6 episode, Normal Again, was Sunnydale, Slayers, vampires, Xander, Willow, witchcraft, Giles, etc etc, all a dream and hulluicinations by a crazy girl, Buffy Summers? And the fact Buffy went on in the rest of the series to be in "Sunnydale" and continued fighting vampires means that crazy girl couldn't get out of her hullucinations, and the doctor, Buffy's parents, failed in helping her.
It makes sense; this crazy girl, makes herself the center of this small town, gives herself a father figure, a sister, several boyfriends, etc. In that episode, they made us believe her being in the hospital was the alternate reality and Sunnydale was the real one. But perhaps Sunnydale is the alternate one, one that this crazy girl Buffy Summers has created.
What do you think? I wonder what Joss W.'s thoughts about that episode and the issue was/were. If anything. This is making my head hurt...lol.
