I agree with jonnyrebel. When you put this song in the context of the rest of the album, you'll find that this song strikes at a perennial obsession of Chad's. He's one of those guys that really needs to know certain things that there's no way of knowing. For example, what the hell happens to our consciousness after our body dies? Chad plays with the uncertainty associated with this by including ghosts in a lot of his songs.
