Brick Wall

I walked through a brick wall today,
And swam in an ocean of sand.
I screamed in a soundproof room,
And got a burn from ice on my hand.
I dreamt of a thousand demons,
And stood at the edge of my seat.
I fought in a battle of peace,
And when I won, claimed my defeat.
I climbed up a tree to the Underworld,
And in the dark my shadow was cast.
So here I will stop at the very beginning,
Which new path will bring up my past.
