I keep waking at night in the freezing cold
Staring at the shadows coming up the walls
Giving me a feeling I can't define
Is there anyone there I say to the dark
But all I get back is a beating heart
Going out of rhythm and I realize
Oh, something's changed
Oh, something's changed
It's just a silhouette, a flick in the blinds
It's just a mind trick, I don't know why
But it reminds me of someone that I used to know
All that I can't forget, is there every night right beside me
I open my eyes and it reminds me
I should have never let you go
Look up there don't you see her face
That familiar heart, that familiar shape
Giving me a feeling, I can't define
Oh, something's changed
Oh, something's changed
It's just a silhouette, a flick in the blinds
It's just a mind trick, I don't know why
But it reminds me of someone that I used to know
All that I can't forget, is there every night right beside me
I open my eyes and it reminds me
I should have never let you go
I wanna put my arms around you
Tell everyone I found you
But you're just a shadow in my mind
You know you've got me so enchanted
Why you gotta be cold-heart
Dancing on your own in the cold streetlight
You're just a silhouette, a flick in the blinds
It's just a mind trick, I don't know why
But it reminds me of someone that I used to know
All that I can't forget, is there every night right beside me
I open my eyes and it reminds me
I should have never let you go
Silhouette, don't change, don't stay
Someone that I used to know, oh someone that I used to know
