Meaning of "Cassius" by Foals

The repetition of "Cassius it's over" and "Cassius away" can be seen as a symbolic representation of the end of a relationship or a significant phase in the narrator's life. The mention of daydreams could signify unfulfilled hopes or aspirations that are now becoming a reality. The repeated mention of accidents may suggest that the outcome was unexpected or unintentional. The comparison of the lighthouse to life and love being accidents could hint at the unpredictability and randomness of certain events. The notion of being second best and wishing for something that's gone away could indicate feelings of loss, regret, or longing for what once was. Overall, the lyrics convey a sense of closure, acceptance, and the acknowledgment of limitations in what one can achieve or influence.
