the first stanza, "dusk" gave ME a mental image and it really was like silence flickering these contrasting images at me...a silent room, the sun setting and it's almost like an eclipse between night and day for me. aluminum walls could be like an inner fortress erected for some kind of protection and once the light is gone, the guards come down? anyways, yes, loved the first stanza. the whole thing is very dreamlike, it has this tone of forgiveness? "Hold hands with the shag if not with redemption." Or maybe resignation? Hmmm, makes one think though!
