今宵离梦
[jīn xiāo lí mèng]
'Separation in tonight’s dream' describes parting scenes occurred inside dreams at night specifically rather than the waking world, carrying the sad undertones and a little bit regret over losing loved persons temporarily even only in an unreal sleep illusion. Maybe it reflects the anxiety and reluctance during separation from someone dear, using the concept of dreams and nights to create an emotional resonance among audience.
