Mirelune

(noun) | meer-loon | Origin: Invented, from "mire" (to be deeply immersed) + "lune" (French for moon)

A serene, melancholic state of mind, often experienced when contemplating something vast, beautiful, and fleeting—such as the night sky, an old memory, or the final moments of a journey.

Listening to the song, he felt a wave of mirelune, as if he were standing at the edge of the universe, watching time slip away.
