Of course, the "anxiety" I mean is not caused by your dream. If you are further anxious because of this dream, your situation will be even worse.
You are constantly being chased in your dreams, which is caused by the "oppressive feeling" in real life. For example, you are often forced, ordered to do something with a heavy heart, often forced to face or deal with heavy things or things you don't want to do, which will lead to this situation.
This kind of mental state is common in office workers who are nervous and tired or students who are under great academic pressure, especially those who are under pressure to enter higher schools.
Your dream is your subconscious desire to escape from "stress", which is just the opposite of your "rigid" practice in reality. This is a psychological protection mechanism. And you have this dream repeatedly, which can be seen as your self-awareness flashing a "yellow" warning to you.
What you need to do now is "decompression". There are many ways to reduce stress, depending on your own specific situation. I suggest you ask a counselor. Find a suitable and correct decompression method. Only by having a healthy and lasting psychological model can we achieve good results in our work and study.
