What does "A Head Full of Dreams" by Coldplay mean?

The meaning of "A Head Full of Dreams" explained in detail by a scholar of literature

Coldplay's new album A Head Full of Dreams is awesome--not only the lyrics, but the music as well. Everything about this groovy disco-experimental album is uplifting as well as dance worthy. refers to Chris Martin explaining that he wants fans to "shuffle [their] feet" to the songs on this album, and as Wife-April and I were listening to it, we realized that even our prime dance style (west coast swing) would work really well with a lot of these songs. (We were pretty excited.)
