Episode
Summary
After being poisoned by a demon, Buffy comes to believe that she is confined to a mental hospital, her mother is alive and her parents are still together and that her life as a Slayer was all an hallucination for the past six years. Deciding that she prefers this 'normal' life with her parents a whole lot more, Buffy attempts to kill the things that tether her to the 'fantasy' life of the Slayer: the Scoobies.

Quotes
Doctor: In her mind, she's the central figure in a fantastic world beyond imagination. She's surrounded herself with friends, most with their own superpowers. Together they face grand, overblown conflicts against an assortment of monsters, both imaginary and rooted in actual myth.

Doctor: Buffy, you used to create these grand villains to battle against. And now what is it? Just ordinary students you went to high school with. No gods or monsters, just three pathetic little men... who like playing with toys.

Buffy: 'Cause what's more real? A sick girl in an institution, or some kind of supergirl, chosen to fight demons and save the world? That's ridiculous. A girl who sleeps with the vampire she hates?!? Yeah, that makes sense.

Xander: When you say poke, you mean -
Buffy: In the arm.

Doctor: It's no use...we've lost her.

Buffy: (to Dawn) You--don't--exist!

Spike: Put some ice on the back of her neck. She likes that.
