Maybe I'm a born optimist 9which I'm not) or maybe it's because I'm desperately in love and sent this song to my boyfriend only this morning, but I read the "in my head" bit totally different as he still says "you might prove me wrong", as in she will show him that it isn't all in his head and in 5 years all of this will be true. Like I said, maybe I'm an optimist

I saw it that way too..
