Is there something wrong with my mother?

So my mom had issues the entire time I was growing up. Anyway, if she is angry at me (sometimes for no reason, she lashes out) she will make things up. Or say that I lied about something that I never lied about. Or say something happened that never happened.... she lies A LOT so that she either makes herself seem right or idk. Then when I call her out on certain things not happening or if I bought something and she didn’t and that something is mine and not hers... she will be like “whatever well I don’t remember either way” or something like that. And I’m 25.... she’s always done this. I just don’t get how her brain can make up so much weird shit? She always has to be right too...
