Lyric discussion by LindsayElizabeth 

Cover art for Dreamer lyrics by My Favorite Highway

Lyric correction from the CD booklet:

"Baby I know you're afraid I'm a leaver But I'm in the fight, here to stay, I'm a dreamer"

The meaning is pretty straightforward. This guy likes a girl who was left by someone she really cared about. She's afraid the new guy is going to do the same thing. He's telling her that he's here to stay, ready to fight, and that he's willing to dream about a future.

And of course, a Casablanca reference. If you've ever seen Casablanca, that line will make more sense to you.

thanks, fixed :)
