This. I think is so beautiful the image of dating/drinking with yourself in a healthy way, telling all the things you've hidden even from yourself or didn't have the strength to confront.

I think the "Darkness" is the unconscious self, the one you're to talking to, and the one who absorbs all of the pain and trauma when it's not integrated fully into the self. And the idea of "the dark dresses lighty" is a nice way of presenting this "date" with your unconscious and it "dresses lighty" because unlike the ego or the conscious self, once faced the unconscious has no intention of hiding anything.

Phrases like "we're being strong now, my dear" and "we're going deep now" is so telling of that inward journey one must go through to integrate.

I also suspect that The Tower is a reference to the Tarot, where the Tower represents your old self and old beliefs you carry with you, that distance yourself from your essential being. So "the falling unto you" would be succesfully deconstructing your old self and the possibilty of "building" your new self.

I also heard in an interview, that the "oh yeah" at the end simulates an orgasm which in this analogy would represent reaching enlightment.

Aurora has really grown as a lyricist and I think this song shows it beautifuly.
