I think this song is about, losing ourselves in our strive to live the life we're made to believe is perfect. We all know we'll get caught in this game, called growing up, sometime because it's the way we're supposed to end up. It's sad to do because with furfilling this purpose we'll lose our early principals and needs and way of life. You win something, you lose something, but we're all destend to believe this is the way it's supposed to go. With reaching this point we'll follow those gone before us, simply because we are destend and used to. We'll pretend in such a way pretending becomes living. We'll live several lifes because one life, in it's own fake existance, can easily be started anew. We'll build up a new life when the other one is trough. Simply because we're able and expected to.
