This song is about transcendence, about leaving behind all of the things that you associate with this world. Thinking and doing something completely new from what you know, that isn't laid out with all the answers of how it works. I think the whole pretend thing is just a way of saying expeirencing the things that don't make any sense to logic. That they have to forget the love they had, because that's the only way to make room for something new. You can't fight the things that are going to happen, because everything runs it's course anyways.
