Where Did That Ambulance Come From?

My parents loved to go for evening rides into the mountains when I was a child. One night when I was about four years old, we were driving in a canyon just outside Denver. There did not seem to be any traffic on the road and we were enjoying the ride. I was sitting on the front seat between my parents Then, for some reason no one ever really understood, I sat up and said, “Watch out for the ambulance.” Startled, my parents looked down at me. A few minutes later, an ambulance came toward us, red lights and siren breaking through the quiet darkness. How did I know it was out there? Was my sense of hearing strong enough to hear its siren? Did I happen to see its lights reflected on a mountain? No one ever knew. I’ve had a few more strange experiences since that time. They still happen every so often.
