This song paints a picture of a complicated and intense relationship, one that feels like a "leap into the void." The singers describe a connection that is both a mistake they want to repeat and a truth that is too frightening to face. They found each other by chance, with one saving the other while they were "falling," leading to a bond so deep they can read each other's minds, even if they don't know exactly what they are to each other.
The main feeling is one of beautiful sadness. The powerful metaphor of a "sea falling from the eyes" describes the tears shed over this connection. Even after "a million nights," the pain and fear remain. The song captures the feeling of a final, decisive moment—an "ultima notte" (last night)—where the desire to forget clashes with the difficulty of letting go, leaving them to wonder if anything will be left of them but dust.
