梦里梦到他梦她梦里梦醒梦中人
[mèng lĭ mèng dào tā mèng tā mèng lĭ mèng xĭng mèng zhōng rén]
This is quite poetic. 'He dreamed of him, she dreamed of her; in dreams awake, in dreams within dreams.' It expresses the complexity of dreams - people encounter various versions of others or even themselves within dreams which symbolize an unreal yet deeply emotional inner world.
