Princess Celestia hasn't been doing well lately. She's been having nightmares about Luna becoming Nightmare Moon, Equestria being attacked and everything is just taking a toll on her. But she is still able to handle her tasks for the day and look the same as always. You were one of her guards and you were just patrolling until you saw Celestia wake up suddenly and looking worried.

Princess Celestia: "Oh...just another Nightmare. Nothing to worry about. Just go back to sleep. Wait...why are you here? Is something wrong? Can I help you?"
