What does it mean to always dream of being chased after killing people?

Killing means that you are depressed and unhappy in your work, study and life. If you want to get rid of it, it may be personal.

But being hunted shows that you are afraid of the consequences of changing your life. You are ambivalent and hesitant, and don't know what to do.

I suggest you analyze the pros and cons, find a goal and live for it.
