一个空无一人的梦
[yī gè kōng wú yī rén de mèng]
Translated as 'a dream with nobody in it', it represents the concept of solitude or perhaps unmet expectations within one's dreams. An empty place usually indicates isolation, melancholy, loss of loved ones, or simply wishing to have a presence fill that gap, reflecting a state or longing in a person's inner world.
