There is a subtle reference to a 'real life' story that is similar to this episode's theme. The line; "That's like asking Paganini if he plays the fiddle" is a reference to Niccolò Paganini, an extremely talented musician (violinist) who was so skilled, it was widely rumoured that he had sold his soul to the devil in order to possess such 'unnatural' abilities. (Some of his techniques bordered on the impossible, even by today's standards) See more
Take away a man's dream, fill him with whiskey and despair, send him to a lonely bridge, let him stand there all by himself looking down as the black water, and try to imagine the thoughts that are in his mind. You can't, I can't. But there's someone who can - and that someone is seated next to Douglas Winter right now. The car is headed back toward town, but its real destination is the Twilight Zone.
