That last line of the chorus might alternately sung as,

You're the only one I'm dreamin' of.

On a related note, I don't think that it's paticularly necessary to follow word for word in a song of this very suggestive nature. It's a fun song. So I think you should have fun with it when you sing it. Alter it as I suggested in the last verse, or as much as you've a mind to, or make up some of your own verses. Go wild and crazy!

wild and wacky weg
