Dream About Mother Rejecting Relationship

I was with my mom and she told me that she didn’t want to have a relationship with me anymore, because she didn’t like me. I was very upset and asked her “so if something happened to me, you wouldn’t care” and she said no. She was very cold, cynical and unkind and didn’t care how I felt about what she had said/decided. I asked my stepfather (her husband) if he had thought about whether or not she may have had an aneurysm or acute-dementia, because I’ve read that sudden changes in personality as well as disconcern for others emotions can be caused by this, but he wasn’t sure. We talked about the fact that it had happened once before. I was shocked by what had happened and wanted my mom to tell my what was happening while I was crying but she didn’t care at all, and said that she just didn’t want to have a relationship with me because she didn’t care about me. She brought our two dogs to me and told me I had to take care of them, because she didn’t want to. In real life we lost one of the dogs a month ago so it didn’t make sense that he was alive. All of a sudden she was back to wanting a relationship with me and acted like nothing had ever happened, like if it was no big deal and she claimed she didn’t mean it and didn’t remember it. I told her that it was going to take time for me to get back to our original relationship, if ever, because everything she said and did hurt me deeply, and I wouldn’t be able to forget about it. I have two older sisters but in the dream I was the only one she didn’t care for and wanted to end the relationship with.
