it's about looking back at childhood. When you're a little kid, every day is like an adventure because there's so much you haven't discovered yet. You believe that amazing things can happen and that a wonderful journey of discovery is about to happen to you. But as you get older, your world sort of contracts, and you get used to the fact that life is mundane and nothing magical ever happens.

It's about wanting to return to a time in your life when you believed in the impossible.
