^But it's called 12 Black Rainbows...
And, I believe in the second line it is supposed to be "but idle" not "unbridled", as the term "idle hands" was used in the previous line...at any rate, this song seems to be about someone who is depressed and suicidal because of some past experience that is vaguely explained. "She" seems like a mother who is addressing a child (the narrator), and the line "there's nothing to fear but the monster is here" might be referring to the mother comforting the child, saying that there are no monsters to get you at night, yet the narrator knows that what will hurt him is inside, either the house (family trauma) or inside himself. The person speaking in the other verses is, I believe, the narrator grown up and fully consumed by that darkness.
