Not certain on the exact meaning but the feeling is that: it could be either a guy or a girl (a guy imo) that has no joy in life ("The fields where nothing grew but weeds"), then finally he does ("I found a flower at my feet, Bending there in my direction.") but even that is temporary ("Inside my hands these petals browned, Dried up falling to the ground, But it was already too late now, I pushed my fingers through the earth, Returned this flower to the dirt, So it could live, I walked away now... ") and that it's too late for him to change ("There's a point we pass from which we can't return") and needs someone to help him ("All because of you,
I believe in angels, Not the kind with wings, No, not the kind with halos, The kind that bring you home, When home becomes a strange place, I'll follow your voice, All you have to do is Shout it out").
I believe though that one song may have multiple meanings, like if one person says its one thing and another person something else it could be both.
And also it's "Lay my head down" (trust me I own the cd and looked in the booklet and I'm 100% certain).
