Steel Train behavior

But now look at my strange behavior
Well, I think I understand
Why those broken roads
Led me to your evil ghost
I'll follow you to any hole
It said
Look at me, I'm nothing but a shadow
What you thought was fear, well, it was hollow
Look at you, you've been chasing shadows
And then I woke up
(Wake up, woke up)
Wake up, woke up
Still don't get all my strange behavior
Can't believe one thought would save me
Save me, girl
Followed her around the world
And when I caught her, she said to me
Look at love, it's nothing but a shadow
Where you saw a heart that was hollow
Look at you, you've been chasing shadows
And then I woke up
(Wake up, woke up)
Wake up, woke up
Wake up, woke up
