Every line is a metaphor. I think the meaning of this song fits great between a father and son bond that has been broken for years maybe even decades. The son finally realizes how perfect his father really was right after he passes away from any form of tragic event. Such as a "car accident" used as an example for a tragic event. But the cause doesn't matter, it's all about the strong emotional impact(the teeth ripping effect) it had on the son who avoided his father for so many years. The love and wisdom the son learned from his father but never really showed any appreciation throughout his fathers life is the "Manna" drug. He realizes you can never have enough "Manna" in your life and enough is never enough. I think that is why they call it "Manna" as in "Man". Not every person deserves to be called a man but the father being described in the song is the father of all fathers. He was more than just a man. He was a dying breed type of man, the kind this crazy world cannot afford to lose. It's why the world is so f'ed up! Nowadays Too many punks grow up to be punks, not fathers. After his father passed, the part about the lord showing him a dream of his daughter crying in his girlfriends/wifes stomach, feeling love again doesn't necessarily mean anyone is pregnant, it just means he now realizes how to pass on his fathers wisdom to his unborn child he will eventually have in the near/far future, that is if he ever has a daughter. I personally picked this song has the most powerful meaning out of all songs in the world to me, and I listen to a lot of music.
