Well it's not too incoherent. It's just an interpretation that the lyrics can take on. The lyrics are abstract in nature and signals to a type of mindset that fully engages in pursuing dreams, enjoying the present moment and to personal growth. The video is a layer of interpretation. If I was being mean, I would say it is a coarse interpretation that makes the above concepts more concrete so as to appeal to the AVICII demographic - the idea of growth, finding a place to belong, and getting lost in a big city, this is a dream to many in the 16-22 age range.
