But+let+the+world+dream+otherwise,

To me, this line sends shivers down my spine:) Not only does it represent that to an outside entity, it would appear as though we are all happy, but we know secretly we are all internally tortured, but it also paints an interesting picture in my mind. (Kind of like conceptual art.) I picture a cold, dreary, cobblestone street, it's raining, and people are just trodding on towards the end, with a fixed mask on them. The mask is struggling with the person's true face, which is frowning, thus distorting our perception, their face, and the world.
