In my dream, I was driving in a city. I thought it was Cincinnati. I decided to take a route other than my usual to leave the city, and I found myself driving on an urban four-lane highway. The odd thing was, all the traffic signs were backwards, as if in a mirror or painted on the other side, away from me. I thought I might be driving the wrong way, but no, there were cars headed in the opposite direction in the lanes to my left, across the median divider, and there was at least one car I could see behind me in the lane to my right.
While I was trying to understand why the traffic signs were all wrong, I saw a pair of highway bridges coming up ahead. They were the usual open-work steel bridges, but instead of driving up onto a roadway, the asphalt shot right up onto the steel, as if I were riding a roller coaster. The pavement stopped, my car was rocketing forward onto the open steel, and as I tried to slow or stop the car, it swerved to my right, and I knew I was going to go off the right side and fall into the water, far below. I shouted, "No, God! No!"
And then I woke up (I thought). For a few moments, I couldn't tell if flying off the bridge was the reality and I was taking refuge in thinking I was asleep in my cabin, or if I were really in my sleeping bag, trying to wake up from a truly wild sleep-ender. Eventually, reality settled on the cabin loft rather than the bridge, and I was glad.
