Dream of traffic jam

I found this sentence from my grandmother's yellow book Duke of Zhou. I don't comment, but I understand:

"There is a scene staring at the traffic in the dream, which shows that the dreamer is trying to solve the problem by himself. It is best to get help or cooperation from others. However, if you encounter a traffic jam, it is a subtle reminder: in the face of the oncoming difficulties, you must stabilize your spirit and patiently overcome it alone. "

Whether it is good or bad, I don't know how to do it, but it is written in the book and there are examples. I've been calling for too long, forget it ~ think for yourself ~
