深知是梦不敢触碰明知是梦依然触碰
[shēn zhī shì mèng bù găn chù pèng míng zhī shì mèng yī rán chù pèng]
Translates as 'I know it's just a dream but I dare not touch it, even so, I still want to reach out'. This conveys strong feelings or hopes one cherishes, although they know these feelings are nothing more than dreams, and may never come true, they cannot help yearning and reaching out.
