I think the song is about the way someone makes her feel. She is probably in love with that person and she compares herself to something so small, like a marble in his pocket. He has control over her because of the way he makes her feel. The part where she sings about her being thrown against the sky and she's raining down in pieces is sort of like the beautiful feeling of being in love. It's a love song in my opinion and it's beautiful.
