Well, I think the pressure of the exam at that time was too great, which affected you too deeply.
Now when we are resting, we are slowly releasing the tension accumulated at that time.
The mood in the dream is that I am worried that I will not do the exam questions, which is also the worry at that time.
In addition, dreaming about exams sometimes reflects that new things in life are testing themselves.
It embodies a challenge and an attempt, but there are some difficulties.
