It seems, especially because of the ending, that the song is about her relationship with her mother. She starts off with a memory from her youth, then it seems to cut to the present- she feels she is aging. Then, another memory, and so on. At the end, "And I'm not a failure, I swear, I wish you could see it from over there" seems like a child wishing the parent would realize their success. With the themes of time, aging, and the poem about her parents at the end, it all gives me the image of a young woman reconciling her "dream like" past and feelings toward her mother.
