Bon Iver's lyrics often delve into abstract and poetic realms, inviting listeners to explore deeper meanings. "21 M◊◊N WATER" appears to reflect on the complexities of life and the passage of time, symbolized through the metaphor of "moon water." The repeated references to "the math ahead" and "the math behind" suggest a contemplation of past experiences and future uncertainties, intertwined with a sense of inevitability. The phrase "Remomrize numb / And half the hum" evokes a state of emotional detachment or introspection. Hiding Berlin could symbolize concealing personal truths or memories in order to rediscover them later. Overall, moon water represents an ethereal, almost mystical element that binds these reflections together, signifying both clarity and obscurity in the journey of self-discovery.
