The Lystra Set

I am afraid there is a ghost in my head.
The world is so strange and everyone in it too.
After a bottle of wine everything's just fine.
I smile and I dance and try to give everyone a chance.
I don't know who you want me to be.
But I'm sure you won't find him in me. Weakest of hearts beat me so brutal.
Input and output put together.
I pass the night and I pass the day to.
I stay awake and wait.
Yes, I do wait for you.
