Walking in My Sleep

I feel like I've been walking in my sleep,
Digging trenches in the pavement
With the soles of my feet.
And I feel like I've been running on gasoline.
I was so cold before I met you,
I was as cold as a machine.

I feel like I've been walking in my sleep,
Chasing shadows, throwing punches
Like stones into the sea.
So tell me haven't I been breathing all these years?
Was I a ghost before I met you,
Or was I even real?
