The main tone of this dream is that the dreamer (your girlfriend) is worried that someone may not approve of you in reality. So who is it? It may be the dreamer's family or friends, or it may be your interpersonal circle. In short, it worries the dreamer, so he resists in his dream. Of course, there is another possibility, that is, the dreamer is a little hesitant subconsciously (of course, the reason may also be caused by family or other reasons), and on the other hand, he feels that it should not be like this, which is caused by contradictions. In short, it is a dream of anxiety and worry caused by contradictions.
So no matter what the reason, you should know and care more about your girlfriend and give her more confidence. She doesn't trust to solve or enlighten her.
