Like me, the characters in Changeling are idiosyncratic and irrational. They see monsters and ogres and dragons and winos and baristas and can't help but wonder whether all of the things they see are real or not. Their memories of their captivity in Arcadia are fragmented and nonsensical. "Did I do this to myself?", they wonder. Are my thoughts of Arcadia really memories or just dreams and nightmares? Why don't they all add up? Is the person who's been living my life while I've been gone the real me? Am I the fake made of straw and glue and dead rabbits' feet? Am I still in Arcadia? Am I stuck in some delusion? How severely will my Keeper punish me when he finds out I've been daydreaming?
Madness is one theme of Changeling, and Beauty is another. There is beauty in Arcadia. It is the beauty of its soft flower beds and the sweet ambrosia of its wines and the airless ice-covered peaks of its mountains. But those flowers are fed on the blood of children, that ambrosia is brewed from the tears of the beaten, and those mountains are littered with the bodies of those who froze to death. The beauty of Arcadia is blood red. There is also beauty in the normal world that goes unappreciated every day. There is beauty in the shyness of a little boy wanting to kiss his first love. There is beauty in the fiery rage of a drunkard too dizzy to control his own actions. When one has been through so much: taken in the prime of one's life, beaten until their bones harden to stone, modified by instruments of painful cruelty and more painful ecstasy, escaped through sheer force of determination and longing to be home, only to find that your self and the rest of the world have diverged so much, there is no more home for you.
To weep at the exquisite beauty of everyday things, to never truly know the difference between reality and your imagination, to be able to walk the dreams of others but to lose yourself in them, to constantly long to be with your loved ones who have been living with some other you the whole time...that is what it is like to be Lost.
