Dreams are generally puns. In addition to growing fear, this dream also contains some anxiety. Let's see what it is.
Elevated overpass, a high-goal link, can also be understood as a way to realize your ideal. Broken bridge fully expresses the dreamer's inner anxiety: what if the ideal in his heart can't be reached!
In addition to highlighting the fear that the goal is difficult to achieve, the dream scene of cars falling down one after another has a deeper meaning.
A car refers to a family in many cases. You see, even the seats inside are for family members. In this dream, cars fell one after another. Is this a metaphor for the crisis of your family (parents)? I can also see my hatred for them.
What kind of ideal goals will young people have? I guess you won't take the college entrance examination soon? Next year?
