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
