I agree with the above comments saying that this song has to do with God, but I think the person she is watching is God Himself. In the album booklet there is a "journal entry" relating to this song that makes it clearer. The person singing is part of an army fighting against something called the "Dread Army" and they have dream that they and their army were dead and part of the Dread Army, the song is describing how the enemies feel. They all then see a man in the sky, presumably God. It is in this context that the words in the chorus are spoken.
