So did you think that everything was a delusion, as seen in the Normal Again episode from season 6? Or was the asylum the delusion?
Back in the 'reality' of the mental hospital, a doctor informs Buffy that she's been hallucinating in the hospital for the past six years and everything she knew to exist in Sunnydale isn't real. She's shaken and confused — especially when both of her parents appear together (with Hank having abandoned his family years earlier and Joyce having subsequently died in the Sunnydale world)... her doctor explains to her parents that she has been catatonic from schizophrenia for all of the past six years (except for the brief period of lucidity which Buffy dimly remembers as her time in "heaven") and that her life as the Slayer has been an elaborate improvised hallucination she has constructed for herself in her mind, explaining what Buffy realizes is its extreme improbability and illogicality compared to the 'mental patient' scenario... Buffy confesses to Willow that in the beginning of her Slayer life, she told her parents about vampires and was put in a clinic for her supposed insanity (a period covered in the Buffy comic "Slayer, Interrupted"). Buffy wonders if she's still there and therefore Sunnydale really doesn't exist, but Willow assures her that isn't true...
