梦中梦见他梦她心中心知他爱她
[mèng zhōng mèng jiàn tā mèng tā xīn zhōng xīn zhī tā ài tā]
Dreaming of him or her within dreams, the dreamer knows that he loves her. It expresses romantic longing and unfulfilled wishes where dreams become a medium for conveying undying love and unresolved feelings between two individuals.
