Inside these walls grows hatred
Inside these walls grows pain
Inside these walls grows anger
Inside these walls I grow insane
Inside this head lives my destruction
Inside this head lives my affliction
Inside this head lives my guilt
Inside this head I live with my conviction
Outside these walls, lies hope
Outside these walls, lies home
Outside these walls, lies freedom
Outside these walls I long to roam
