United we stands , dibided we fall what part of speech is it?

I am not exactly sure what you mean by that but I think the answer you are looking for is:

it is a motto, usually used to bring people together. Strength in numbers. two is better than one

it does symbolizes love,   lust   and dreaming and is seen as a power symbolic force that determines and affects human behaviors and reactions.

in the context of the question it does remain you that he events are only taking place at night and the reader of the passage of time."
