This dream has a psychological compensation function, that is, as a third party in life, you are really uneasy. Being humiliated in the dream is a means to balance your mentality and avoid the feeling of guilt and anxiety leading to more serious physical and mental disorders.
The symbolic meaning of the umbrella is actually in your heart. That's what "scattered" means. The dream means that his wife wants you to leave him and want you to "break up".
Of course, it can also be said that this dream has a warning significance, that is, if the relationship in your life has not been discovered by your family, then this dream reminds you that if you persist, you will inevitably be discovered and humiliated in your dream.
We only interpret dreams according to dreams, and it is not good to comment too much on real life, because there may be many factors we don't know.
