Cover art for Only If for a Night lyrics by Florence + the Machine

After listening to this song for the hundredth time, I think I have formed my opinion on what this song is about. It's obvious from Flo's other songs that she has battled depression. Her grandmother committed suicide. Perhaps Flo was going through a particularly dark time, contemplating suicide, self harming ("My body was bruised and was set alight). In this dark time, her grandmother came to her, in a dream or in her imagination, to help her through it, convincing her not to hurt herself (And you told me I should concentrate), to fight through her depression (And the only solution was to stand and fight).

This is an absolutely beautiful song that carries so much meaning for different people. My interpretation may or may not be right but that's how I see it.
