So, I think you are a very rational person. You are good at controlling yourself in your daily life. Even if you encounter provocative or unsatisfactory things, you will treat them rationally. At the same time, you are very responsible and considerate of your family. Of course, no matter how strong the control is, there will be an impulse to attack if something goes wrong. So you don't have to pay too much attention to the plot suggestions inside.
Of course, you may also ask why you have this dream now. This is because you may have been affected recently, such as something that makes you angry or thinking about similar problems.
As you said, the murder in the dream is something that many people will encounter in their dreams. If you look at the problems here carefully, many people will have similar situations. This is a normal psychological reaction.
