Dreaming of a coffin means that you may have been under a lot of pressure (including emotions) in your life and study recently, almost to the limit. I hope you can find out the reason carefully and adjust it in time.
Of course, someone has upset you recently, making you angry and unhappy, so there is such a thing as carrying a coffin and breaking it in your dream, and even you feel very anxious and helpless in your dream. Pay attention to traffic safety when traveling.
I usually have this dream when I am in a bad mood or too tired, and I feel the same way. Don't take it to heart, be careful in everything and be patient with others. (Coffins generally refer to villains)
