我心知你我梦知心
[wŏ xīn zhī nĭ wŏ mèng zhī xīn]
'I know you in my heart and you know me in my dreams' means two individuals understand each other very well spiritually despite distance apart physically; they are closely connected internally even when separated externally. Such understanding could also occur within one individual during the day versus night states or subconscious level. This username highlights profound mutual comprehension between people or souls.
