Cover art for Echoes of Mine lyrics by M83

It's clear the narrator is an elderly woman, and I think the first line, "it is late," alludes to that. As she reminisces about her life, she imagines her memories as a forest. In her mind, these memories are a living thing with the power to transform. Even though she is now old, she can travel to a place in her mind and remember herself as that 20 year old girl with the unblemished hands and smooth face who loved like she has never loved.
