你是黑夜我深深的闭上了眼
[nĭ shì hēi yè wŏ shēn shēn de bì shàng le yăn]
'You Are Night, I Shut My Eyes Deeply'. This signifies giving into someone completely, almost surrendering oneself during intimacy; or possibly shutting off from the world in presence of someone - choosing darkness and seclusion as opposed to light and openness. It can also suggest a state of complete relaxation around this person.
