It does sound to me like you feel you are meaningless to your family or that they are giving you a hard time or excluding you and your daughters.

But the part where "independent" people see your mom's side and turn against you, makes me feel you are not feeling very good about yourself. Since it is our own dreams we are dreaming, we set them up and are all the people in the dream. That you "let" your mother win in your dream does not sound like your self esteem is doing too well right this moment?

I think if they were my dreams, I'd look at all the current conditions in my real life since the dreams started and see what specific problem I'm feeling helpless and angry, bitter, disappointed about. I'd try think of one thing I could do for myself to counter those feelings and help my self esteem. I don't think the recurringness will go away until you address it in your real life?

I forget. Do you have a T you could talk to about the dreams? I use to learn a lot from my dreams when I was in therapy, they would structure themselves to give me more information so it was like I could work on my issues at night too :-) Was helpful but not always fun. Some dreams are hard to face and work with but that you gave them to yourself means it's possible to work with them; your unconscious wouldn't have presented them to you in a way you couldn't or that wouldn't help if you can only decode them! Good luck.
