深知是你是梦我怎敢触碰
[shēn zhī shì nĭ shì mèng wŏ zĕn găn chù pèng]
'I know well you're a dream - how can I dare touch you?' reflects the knowledge that an object of love is too perfect or distant to ever attain. The user longs but remains wary and cautious about pursuing, fearing shattering an ideal image.
