I Don't Understand

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
 Suppose the feeling's real
 You'd never know
 Suppose it's what you feel
 You'll never 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
 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
 Suppose the feeling's real
 You'd never know
 Suppose it's what you feel
 You'll never 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
 I open my mouth but there's
 Nothing to swallow down
 I'm scratching my face like there's
 Something, farther down
 It's like a drug
 I turn the light off
 And pull the plug
 But still it always comes back on
 Suppose you change your mind
 And back again
 Suppose you had more time
 And adrenaline
 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
 What I don't know
