One day I was walking and not watching where I was going and fell into an open sewer pipe. There was murky green water inside. Carefully, I swam to find an open exit because the one that I fell in through got closed. So while swimming to find an exit I moaned and groaned and wished that I had watched where I was going while I was walking.I didn't want to be in this disgusting place. It had bugs and disease just waiting around the corner. Suddenly, a horse came galloping down the tunnel like a skater across ice. Then I realized I was dreaming.
