(Just a little side note, my father is very abusive and controlling, and I hate him and his presence in my life.) I always dream of me and my father sitting in the dining room, when he talks trash about my mother, and always threatens to take my brother away from me (he knows my brother is my weakness and I cannot live without him because he's 10 years younger than me and my only sibling.) Then I talk back and start screaming and recounting all the horrible things he has done to us till date and also ask him if it doesn't hurt his conscience. Then I see he tries to hit me, but I hit back and keep hitting him. But when I am hitting him, he's neutral, doesn't bother at all.
This dream seems to be a reflection of your suppressed emotions and feelings towards your father's abusive and controlling behavior. The dining room symbolizes a place of gathering where family members come together and share meals. However, in this dream, it represents a place of tension and conflict between you and your father.
Your father talking trash about your mother and threatening to take away your brother may symbolize his attempt to manipulate and control your family members. Your reaction of screaming and recounting all the past hurts and wrongs that your father has done to your family indicates your strong emotional response to his behavior.
When you hit your father and he remains neutral, it may indicate your frustration and anger towards his lack of acknowledgment and remorse for his actions. The dream may also suggest a desire for justice and the need to stand up for yourself and protect your family, especially your brother.
Overall, this dream may be a reflection of your subconscious desire to confront your father's abusive behavior and protect yourself and your loved ones from his control. It is crucial to seek support from trusted friends, family members, or professionals to help you deal with this situation in real life.
