Verse:
Db
You've been deep in a coma
But I stood right here
Bbm
When you thought there was no one
I was still right here
Gb
You were scared, but I told you
Ab                  Db
"Open up your eyes"
Db
Never stopped being someone who could love you well
Bbm
Had to show you the hard way
Only time will tell
Gb
Revelations and heartaches
Ab              Db
make you realize

Pre-Chorus:
           Bbm  Ab     Gb
That I was always in front of you

Chorus:
Db
So wake up
              Bbm
Your sleeping heart
        Gb
I know sometimes we'll be afraid
                          Ab
But no more playing safe, my dear
I'm here
        Db
So wake up

Your sleeping heart

And we will dream a dream for us
                            Ab
That no one else can touch, my dear
I'm here
        C
So wake up
