It is also possible that you have a good impression on her, and the wedding scene and your feelings for her blend into one scene. Dreaming is illogical, but the subconscious mind releases it at will, and crying has two explanations: 1. Pear blossoms bring rain, and people sympathize with them. This is a release point of your feelings. 2. You did something that you consciously felt ashamed of your wife or subconsciously thought you should treat her better, but you didn't do it.
Never mind, just seize the opportunity and turn your love for your wife into practical action. As long as there are no regrets.
