WHAT IS THIS SONG?!?!?!?

So there's this song that I heard a LONG time a go and I Kant remembe the name of it. It sounds "dreamy" if you will. VERY dreamy, like a lullaby. It's a woman singing. It kind of reminds me of John denvers "leavin on a jet plane" but you can disregard that if your suggestion doesn't. As for the the lyrics, I remember something about a magic carousel and seas rising up and down. It's a weird song. So anyway, thanks!
