I think this song is about the inner darkness that seems to live as an entity within every one of us. Once you begin to recognize it or fear it, it overtakes you, or entraps you (the walls). They are saying that if you can free your mind from the darkness that overcomes so many people, then you will free yourself from guilt and wrongdoing.
