she was tired of sleeping

I think Fight Club (the movie) is brilliant, and yes I recently bought Invisible Monsters, but I never really read a Palahniuk before. However, thanks to Twitter and its quote-happy inhabitants, I found a good quote from Palahniuk's Haunted:

“What matters,” Sister Vigilante says, “is, people need a monster they can believe in.”
A true and horrible enemy. A demon to define themselves against. Otherwise, it’s just us versus us.

So it is okay to have demons in my head. Because otherwise, I'd just be battling myself :)
