Amy explains in an interview that this song is about passing over to the next life:
"I love the song, I think that it expresses a little bit of a new emotion for me, for Evanescence. Because it's sad, it's goodbye, it's sort of from the other side of the song before. It's like from the person's perspective that's moving on to the next life. But it's peaceful, it's an acceptance of that giant crazy thing that fascinates me, that I wonder about and think about. And it's like, life and death and what comes after, you know and what does it all mean. So it's that acceptance and peaceful feeling like the calm after the storm."
The song was submitted for the soundtrack of the 2008 Japanese animated fantasy movie Ponyo, but wasn't accepted.
