梦里梦到醒不来的梦梦里梦见梦不见的梦
[mèng lĭ mèng dào xĭng bù lái de mèng mèng lĭ mèng jiàn mèng bù jiàn de mèng]
Dreaming in dreams about dreams one cannot wake up from, and in dreams dreaming of dreams unseen - this conveys the complex state of mind where dreams intertwine with reality and there are many desires and aspirations unattained, expressing helplessness and yearning for dreams and aspirations.
