Am I Alone In Here lyrics by Chevelle

I think that that the one singing the song is talking to himself, or thinking, because his love or lover has left a note saying possibly something along like lines of her leaving. His sister must have called and told him that the girl is coming, or came. The note obviusly says so, also. Possibly, they had sex on his bed, and she left before he woke up. He's sad because she left? And he can't breathe because of that? Hey, I'm just guessing on what I think it is. Anyways, the man knows he can't look at the chick the same anymore, because of whatever it is she did. He wants to "wake up", or in other words, see the sun, you could say. He also wants to take away the feelings he had for her, trash those, and the depressing ones, too. Seems good to him, right? He's gonna break down (that was easy to tell), and he does not care if she shows up and sees him crying, etc.. And he's gonna keep screaming, asking, saying, thinking, etc. "Am I alone in here?" That's what I think anyways...
