[Verse 1]
C
You've been deep in a coma, but I stood right here
Am
When you thought there was no one, I was still right here
F
You were scared but I told ya, open up your eyes
C
Never stopped being someone, who could love you well
Am
Had to show you the hard way, only time would tell
F
Revelations and heartaches make you realise

*RIFF*

[Pre-Chorus]
      Am G      F
I was always in front of you

[Chorus]
        C                 Am
So wake up, your sleeping heart
            F
Sometimes I know you'll be afraid
                             C         G
But no more playing safe, my dear, I'm here, so wake up
