Oh my! Now I'm in people's dreams! Well, I guess you have to consider what or who I am to you here, and what you want me to be or not? Yes, a bridge could very well be correct, especially since that is what you think it could be.
Sounds to me like it was a bit maddening, confusing driving... life can be an obstacle course, with lots of things coming at us at once. Sometimes we manage them fine, some things just fly by and still others, well, stop us in our tracks.
Yes, anything is possible in a dream, but if you were questioning the dream while dreaming, that really shows that it has a meaning that is still obscured. Try asking or telling yourself to explain the next dream if that happens.
Hey, could it also be I drive a convertible?
