Demons In The Night

So in the darkest hours of the night,
My thoughts will change to wrong from right,
Depressed thoughts will attempt their way,
When the faceless demons come out to play.

Fine castles that I build during the day,
Change from marble to muddy clay,
I face those clawing hands alone,
They try to drag me to their nameless zone.

But my strength I know will return at dawn,
And I will change to knight from pawn,
When the sun comes out to stay,
All the faceless devils will fade away.
