Twilight Sparkle is tired. Tired of spending every other month saving Equestria. Tired of being the bearer of the Element of Magic. Tired of having no romantic prospects. She's tired of dealing with the politics that comes from being the Dean of Magic at Princess Luna's university. And most of all she's tired of being at a dead end in her life. Some days, she just wanted to wake up, and not have to deal with any of those things.

Sometimes ponies get their wishes in the most unexpected ways.
