The Demon in My Head

There was a demon in my head
Who danced at night and slept in my bed
When it got bored of having it's way,
It prayed for light, and it let it stay
When the light began to grow
It pretended not to know
When the ignored morphed to joy
It plotted a treacherous ploy
When the joy transformed to love
It pulled on an iron glove
When the glove melted with light
It feared such mysterious might
When the light an angel unveiled
It panicked, all its plan revealed
When the Angel taller grew
It packed up its bag at night and flew
Now and again it cries anew
It's voice from a distant place, repeating
"If only I knew, if only I knew..."
