The man in the dream is actually your imaginary enemy, which you can understand as "the consequence of failure". He has your girlfriend, and you are angry but helpless. When your girlfriend smiles at you without answering, she is telling you that "this is the result of failure". He holds your photo album, which can be understood as your most precious thing. Your mother wants to seek outside help on your behalf, but it's obviously useless. They laugh at you with your most precious thing (your dignity). In the dream, your girlfriend's behavior (smiling without saying anything) means "that's it".
So in general, you are worried that setbacks in your career will make you lose your dignity. Career always has ups and downs, so we must adjust our mentality. Anyway, we are not poor enough to beg, are we? Li Ka-shing was also a viscose flower at first. Come on, believe in yourself.
