[Verse 1]
When I'm asleep
I leave the light on
And try to breathe
Relive the moment I was born
I feel the breeze
It feels electric
Then mockery
Another headache I reject

[Pre-Chorus 1]
Suppose the feeling's real
You'd never know
Suppose it's what you feel
You'll never know

[Chorus]
That's what I don't understand
That's what I don't know
That's what I don't understand
That's what I don't know

[Verse 2]
Now I'm awake
I leave the light on
And take a swim
Beneath the rocks and undertow
I try to scream
I don't remember where I've been
A trampoline
Another lack of oxygen
[Pre-Chorus 1]
Suppose the feeling's real
You'd never know
Suppose it's what you feel
You'll never know

[Chorus]
That's what I don't understand
That's what I don't know
That's what I don't understand
That's what I don't know

[Bridge]
I open my mouth but there's
Nothing to swallow down
I'm scratching my face like there's
Something, farther down

[Verse 3]
It's like a drug
I turn the light off
And pull the plug
But still it always comes back on

[Pre-Chorus 2]
Suppose you change your mind
And back again
Suppose you had more time
And adrenaline
[Chorus]
That's what I don't understand
That's what I don't know
That's what I don't understand
That's what I don't know

That's what I don't understand
That's what I don't know
That's what I don't understand
That's what I don't know

[Outro]
What I don't know
