Nora Seed is walking through a smoke-filled, burning library, attempting to reach a particular aisle despite nearly choking on dust and falling debris.
The library, which is burning and falling around her, represents her various potential lives, each life represented by a book.
A piece of debris hits her, causing Nora to fall and lose her pen, but she refuses to give up.
She sees one book untouched by the fire and manages to retrieve it, realizing it's empty, symbolizing her unwritten future.
Even in the midst of the burning library, she recognizes the potential in her life and determines her life, as it is, is what she wants.
Encouraged by Mrs. Elm's voice, and disregarding the falling debris and encroaching fire, Nora struggles to write in the book and chooses to live.
After several unsuccessful attempts to trigger a response by writing different phrases, she writes "I AM ALIVE," signifying her affirmation of life against all odds.
Immediately after writing this, the entire library crumbles and dissolves into dust, symbolizing the end of her internal struggle and the beginning of her acceptance of her real life.
