State-interstate-state of mind

Example: I’ve had a recurring theme in my dreams involving highways for some time now. Sometimes I’m walking on twisted, closed down structures and ramps in the city, or on a path alongside a Midwest interstate. Recently, I’ve been walking alongside quieter state highways.

Example: I usually seem to have a positive feeling. I don’t mind walking, and I enjoy seeing the different perspectives and challenges of walking a road that most all people drive. If anything, I don’t appreciate being seen walking by the other drivers.
It’s usually daytime or evening in these dreams. I was wondering if there is any particular significance in having this variety of dream recur so many times.
