Is It All In My Head

I hear the flutes playing I hear the children laughing Is it all in my head I see the shadows move along the walls I see the ghosts in the halls Is it all in my head Sometimes I think nothing is real Sometimes I have got nothing to feel Is it all in my head Some days I think I have already died Some days I think there is a demon inside Is it all in my head I can see the world is on fire I can see that every one is a liar Is it all in my head
