I think the singer of the song is the moon. She always wanted to be the Sun, maybe even thought she was the Sun, until she realized her light wasn't hers. She knows that no matter how much she wants to be the Sun, she never will be. But she still wants to be the Sun. And metaphorically, it's how we all wanted these dreams that society feeds us as children...but they're all just borrowed from the popular conceptions, and they'll probably never be real, and never be ours. But we still want those things.
I think MsChizzy has hit the nail on the head.
