Dream of sofa, bedroom, dead mother, child, hands, woke up, mother

I dreamed that my dead mother was alive. We were in our family home and my mother and I were arguing. My mother had a seven year old little girl in her arms. She had blond hair. My mother was complaining that her back was sore and she tried to hand the child to me. I got up off of the sofa and I told her that she was a bad mother. She had not been a good mother to me when I was growing up and that she wasn't fooling anyone with her saintly mothering act. I started to walk away and I felt my mother behind my back, my mother was looking for something to hit me with. I turned around and started yelling at my mother. She went to hit me and I grabed her by the neck and started to choke her. I was yelling at her and she said something to me. She took her hands off of my hands and I let her go. We were standing at the top of the stairs and she fell backwards. I turned away and ran up the stairs to the top floor. I ran into my mother's old bedroom. There was no furniture in the room and the room was much larger in my dreams than it actually is. I called someone that I do not like and was crying and telling her that I did something bad and that I needed to see a lawyer. I woke up.
