Cover art for Afraid This Time lyrics by Celldweller

I've always thought that this song was about mental walls. When you've got walls, all you want to do is break them down, but you're afraid to because it's all you've ever known. You can keep whoever you want out if you've got them - no one can hurt you because you don't allow anything good or bad into your life.
