Seeing a friend's family of three is your desire for love. Children, the symbol of love and responsibility, you "can't hold on", which shows that you are hesitant to step into feelings, fearing that you can't bear it.
Plums and durian, if eaten in the mouth, are also symbols of love. Because eating and drinking in dreams are related to sex, according to Freud's theory, the "mouth" of the dreamer's body can be replaced by each other, so eating often takes the place of sexual organs to accept other objects, that is, disguised and modified sexual behavior. Dreams are subconscious works, so they often express their inner feelings with more direct sex.
But in the dream, you didn't eat it in your mouth, and you were still hesitating to eat it. I want to know whether the fruit of love is bitter or sweet.
Ps: If you get married, the question is whether you should have children.
