In my dreams

Last night I dreamed I was driving a car, and up ahead I saw a little girl walking her red Shetland pony along the city street. A man walking ahead of her took a last puff of his cigarette and tossed it on the ground, The pony stepped on the still lit cigarette and took off running. The little girl was dragged a few feet as she tried desperately to hold on the the lead, but then the pony broke free. I turned my car left and saw the girl being helped by a stranger, so I drove as fast as  I could in hopes of saving the pony. But when I turned right, I looked down onto the highway, and it was too late-the pony had been hit and was dead.
