Even if dreams can show us the future, this dream did not make sense. Must I never pass a lorry on a clear road? Can a dream show us the future and give us the opportunity of changing it? It is hard to believe. If we can see the future in a dream, then surely the future already exists. If it does, then we are not free to act in the ways we wish to, we are not responsible for our own lives. Before I tell you the dream, I must explain a little about the context. It was the summer of four years ago, and I was driving my family back from Italy through the south of France. My son had not yet learned to drive, my daughter was too young, and my wife doesn't drive at all. I had been at the wheel for the best part of three weeks. Perhaps I was tired; perhaps I could think of nothing except cars. We spent the night of the dream in a town called Tain l'Hermitage. Now I'll tell you the dream. I was sitting in a big, powerful, cream-colored car, and I was driving at high speed through the country. I was coming to a bend in the road, and in front of me, there was a very large lorry. My foot reached out towards the brake, but it could not find it. I looked down: there was no brake! Worse: my hands held empty air. There was no wheel for them to hold. There were no controls of any kind. Already we were almost into the back of the lorry. I shouted in fear. Then I heard a calm voice coming from my left, and I turned my head. A stranger was sitting there. He was a cheerful man of about forty. He was wearing an expensive shirt, and on his head, he had a red hat. I couldn't understand what he said; he spoke very quickly in French, and my own French is not very good. I didn't, in fact, care what he said. My eyes were on his clean, fat hands, which were holding the wheel. This car had its wheel on the left. He, not I, was in control.
