Might I suggest a title for your poem?

It speaks to me of dreams, of our happy places that we go to at the end of a tiring day. Places we go to with our love and sorrow (our aching lungs cast into a sky of wings) and dream of better places where we're happy (and for the first time we can truly breathe)

So, I see this poem as wishing good night.

Potential title: Good night. :)
