You feel a breeze but from nowhere

You hear a laugh but nothing's there

I show up when you're unprepared

You know I like to see you scared

I'll be right behind you

No matter where you go

I'll be there to surprise you

And I just want you to know

I'm the monster underneath your bed

I'm every thought inside your head

You can run but you can't hide

No, not this, no, not this time

I'm the itching underneath your skin

Can't stop me from creeping in

You can run but you can't hide

I am already inside

Oh-oh, oh-oh-oh-oh-oh

Oh-oh-oh

Deep down, you want me to stay

You'd get bored if I didn't play

It's really why you're so afraid

You want me watching night and day

I'll be right behind you

No matter where you go

I'll be there to surprise you

And I just want you to know

I'm the monster underneath your bed

I'm every thought inside your head

You can run but you can't hide

No, not this, no, not this time

I'm the itching underneath your skin

Can't stop me from creeping in

You can run but you can't hide

I am already inside

Oh-oh, oh-oh-oh-oh-oh

Oh-oh-oh

I feel the tremble in your touch

I'd take it off, but it's not enough

I need to feel that twisted rush

And if you scream, I'll make you hush

I'll be right behind you

No matter where you go

I'll be there to surprise you

And I just want you to know

I'm the monster underneath your bed

I'm every thought inside your head

You can run but you can't hide

No, not this, no, not this time

I'm the itching underneath your skin

Can't stop me from creeping in

You can run but you can't hide

I am already inside

Oh-oh, oh-oh-oh-oh-oh

Oh-oh-oh

I am already inside

Oh-oh, oh-oh-oh-oh-oh

Oh-oh-oh
