First of all, you may be under a lot of pressure (including emotions) in your life, work and study recently, almost to the limit. I hope you can find out the reason carefully and adjust it in time.
Of course, recently, someone has made you upset, angry and unhappy, so this kind of thing appears in your dream, and even you will feel very anxious and helpless in your dream. Beware of villains and 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.
But you didn't get hurt in your dream, which shows that you have the ability to handle bad things, but you should pay more attention.
Besides, subconsciously, you miss grandpa. Grandpa loved you very much before his death. It is best to pay homage to him.
