Reincarnation is a religious belief that, after a person dies, their souls are brought back to life. Maybe in another form, a different time, or a newly constructed life.
Tracy Drake McColt always denied the realism of reality, she counted it as merely just another dream. She fancied fairy tales, with her unique definition of a fairy tale of course, since then again it wasn't any different from reality and dreams. They are all just a story that starts with once upon a time and ends with happily ever after.
She is driven away by her disbelief in reality, her disgust with the imperfections in her life, and her fear for the lives of those she loves. But she wakes up to find an entry in her diary, one that starts and ends -ironically- her life.
