So your question is, why do you always dream recently? In the dream, someone wants to arrest you.
So personally, do you always worry that someone will arrest you? Did you do something? If you commit something, I personally think you should take the initiative to turn yourself in and tell others that I did it. I am not good and should be forgiven!
If you have done nothing wrong, don't be afraid. Then this is just a dream. Dreams are often contrary to reality, so if someone catches you in a dream, then in reality you must be a down-to-earth person and a bookish person, so you don't have to be afraid.
So the above is a simple answer to your question. I hope I can help you and you can adopt it.
Finally, I want to wish you health, happiness, good luck and all the best.
