One is darkness, One is light

When I am waking up, I am still asleep
My eyes are open, although my eyes are closed
I arise and wonder who will I be today?
Maybe I will be the one I am, or the one I am?

I am two but there is just one soul
Just one heart to supply us both
I don’t know who I really am
All I know is that I will always change

One is calm, the other's wild
We both have dreams and things undone
Now you see me now you don't
I am a human chameleon

It's hard to find a friend
That can cope with what I am
One day every mothers dream
The next I practice the pain extreme

One is darkness, one is light
What I create I will ignite
I am the sheep, I am the wolf
Someone locked me in this cage and threw away the key
