In the song "Graveyard" by Halsey, there's one line that goes like this:
You look at me
With eyes so dark, don't know how you even see
You push right through me
The song overall is about someone in a relationship with a person who's heading into a bad place (mentally) and their partner following them there.
But what does this line about "dark eyes" mean? Is it referring to physically dark eyes, like from lack of sleep? Or what?
