When I sleep, I want to be completely undisturbed. That means, absolutely no light creeping in around the curtains. And I don't want to be woken by the sound of motorbikes or sirens though a single pane of glass.
Bedrooms should have an inner sanctum; A smaller room within a room, with just enough room for a bed. It should be acoustically treated, and completely isolated from sound and light.
