Cover art for Undertow lyrics by Warpaint

i think throughout the song the singer is singing in third person

"Your brown eyes are my blue skies. They light up the rivers that the birds fly over. Better not to quench your thirst. Better not to be the first one diving in, though you caught me and you know why you breathe in the deepest part of the water."

basically she's saying do not fall in love with this guy even though he's so wonderful "What's the matter? You hurt yourself? Open your eyes and there was someone else Now i've got you in the undertow. Now i've got you in the undertow. Why you wanna blame me for your troubles? Ah ah ah you better learn your lesson yourself. Nobody ever has to find out what's in my mind tonight."

and this stanza she's taunting herself because i guess she did fall in love, even though she didn't want too because she knew he was going to be a disappointment turns out he is, he isn't who she thought he'd be

pretty much unrequited love she loves him, but he doesn't love her or she fell in love, and now is regretting because it's not what she thought it would be now she's hurt, and she's like "i warned you" to herself now her emotion have ahold of her, and are puling her in

and she asking herself why blame her emotions, she cannot help it and she telling herself to learn the lesson on her own and not to drag the guy into it, because he isn't to blame but herself because she didn't listen to her intuition in the first place

and basically it's a internal battle, and no one knows that she's having this struggle inside her head no one knows she's hurt individual vs them self kind of thing

"Let tonight pass us by. Do you really want to be the one to fight? And i said "You're better not to light that fire. It will take you to the darkest part of the weather." she's saying, let this night just end don't have to remember anything do not have to do anything just going to waste away tonight she asking herself, do i really want to fight for this guy try to have him i told myself not to let something happen because it's only going to end up bad

"Nobody in my mind. Nobody in my mind. I feel it in my heart tonight."

she's trying to convince herself to let go and crap but she still feels this love for him in her heart

"I lay on the floor, pressing in my eyes. Seeing little lights. Please light these decisions that only one could make I wanted to stay home but i went running running running running from the troubles running running running running from the troubles running running running running from the troubles runningrunningrunningrunningrunningrunningrunningrunningrunningrunning"

basically the entire song is brain vs heart, do i listen to my brain or to my heart she mentions that only one could make the decision but she doesn't know which one

so she decided not to make a decision and just run
