Because someone in my family is a psychology major, I dream like you, always asking about the meaning of dreams and the unconscious thinking generated by dreams. I often dream about cats.
Giving up what you like but don't like very much means that you will face some choice problems. Like begging a to abandon b or something.
Cats go to other cats, that's what you want you to give up and have a good development.
Of course, dreaming about cats often means bad luck, but I don't think it means anything to us cat lovers.
I hope I can help you! Be happy ~ _
