《The Spectre》的英語詞曲由黛米·洛瓦托和卡莉·蕾·吉普森共同創作，並由黛米·洛瓦托和瑞恩·唐尼負責演唱。其歌詞如下：
Verse 1:
Shadows in the moonlight
It's just a bad dream
But you don't wake up
Your mind's gone blank
The fear of the unknown
A voice in the night
It's calling your name
Chorus:
Spectre, you're haunting me
You're the shadow on the wall
You're the story in my head
You're the reason I can't fall asleep
Spectre, you're all I see
When I close my eyes
This ghost of the past won't let me be
Verse 2:
There's no closure
No answers to be found
But you're still here
In my mind, in my head
It's like I can feel you
Right beside me
But it's just a dream
Chorus:
Spectre, you're haunting me
You're the shadow on the wall
You're the story in my head
You're the reason I can't fall asleep
Spectre, you're all I see
When I close my eyes
This ghost of the past won't let me be
Bridge:
Oh, I try to move on
But you won't leave my mind
You won't let me go
Oh, what am I supposed to do?
I can feel you calling me
I can hear you whisper
Come back to me, come back now
Chorus:
Spectre, you're haunting me
You're the shadow on the wall
You're the story in my head
You're the reason I can't fall asleep
Spectre, you're all I see
When I close my eyes
This ghost of the past won't let me be.
