一日一夜一场梦一生一世一轮回
[yī rì yī yè yī chăng mèng yī shēng yī shì yī lún huí]
This suggests that life consists of many phases much like different dreams over a day and night, while also alluding to the idea of reincarnation where our entire life may seem just as fleeting and unreal in the larger scheme of existence.
