I'm sorry nobody else has so far given you any help. Hopefully they will soon?
But for me, I think you and me have a basic misunderstanding here. You think the dream is advising you on what to do.
I think the dream is simply expressing that you are in a position where you don't know what to do. You feel you can not say what you need to say. That is what the dream is saying.
It does not tell you how best to proceed. That is your decision.
Sorry.
I think what would help you, is to take some kind of course in self-assertion, so that you can manage to take more control in your life without causing great offence. Then you would be less taken for granted.
Or the very easiest way: simply tell the person/people concerned, very calmly, how you feel. You know? Don't accuse them, don't get angry, just tell them. "I feel that I am being taken for granted." See what they have to say.
All the best,
Tish
