How interesting! I had a dream about a peacock just last night.
I had a dream about a peacock attacking my father and my father was yelling and screaming. This probably means that he is being overly self-deprecating in his behavior, right?

Interpretation:
This interpretation you gave is correct, but it does not mean that you need to explain your dream to your father. It is about avoiding a bad behavior pattern that your father has and that causes him to have a conflict of interest.
This behavior pattern can be similar to the characteristics of a peacock. Knowing where to show and where to hide the positive aspects of life, talents, and abilities, is a psychological skill that can be acquired gradually
