[Verse 1]
Shine the flashlight, check the halls
Run back, behind the bed, and I'm already dead!
Nightmares, nightmares inside my head
They had no flesh to seal the deal
The freaking door, shut down, they’re dangerous
Jump-scare, they're the devil

[Chorus]
What's behind this door?
Do I really wanna know?
Nightmares cause problems in my head
What’s behind this door?
Do I really wanna know?
What did I do to deserve this?
I really don't even know
What's behind that door?

[Post-Chorus]
I'm looking, looking around
This place is a nightmare
Am I inside my house, or in an asylum?
Is this reality, or a fiction from my head?

[Verse 2]
Run to the closet, the door!
(I don't like animatronics anymore)
The more, the merrier they say
They could use upgrades
What the hell's behind the door?
[Chorus]
What's behind the door?
Do I really wanna know?
Is it animatronics, or my parents here to send me away?
What's behind this door?
I really, really wanna know
I’m scared to open it
What’s behind this door?

[Verse 3]
This all happened one dark day
My brother decided, he chose someone else over me
It was my birthday in the eighties
Nightmares that I've never seen
I didn’t know my one special day
Would cause so much harm over me

[Pre-Chorus]
What's behind this door?
Do I really wanna know?
What's behind this door?
Do I really wanna know?
What's behind this door?
Do I really wanna know?
What’s behind this door?
Do I really wanna know?
[Chorus]
What's behind this door?
Do I really wanna know?
The end, question mark?
This isn't the end really

[Outro]
What's behind this door?
Do I really wanna know?
What's behind this door?
Do I really wanna know?
What's behind this door?
Do I really wanna know?
