What does it mean that "floating life is like a dream and floating dust is empty, which is the geometry of happiness"?

Meaning: Life is like a dream, floating and sinking in the air, and there are many happy times.

"Floating life is like a dream, floating dust is empty, and it is a happy geometry." From Li Bai's Preface to the Peach Blossom Garden Spring Banquet.

"Brothers Peach Blossom Spring Banquet Preface" wrote:

The husband of heaven and earth, the inverse of everything; Time flies, and a hundred generations fly by. And floating like a dream, for joy geometry? The ancients walked by candlelight at night, not bad. Kuang Yangchun told me to smoke, and I made a big fake article. It will be a peach blossom garden and a happy family. Tuan Ji Shuai, all for Huilian. We sing, and we are ashamed of our happiness. You didn't get a reward, you can tell me. Give a banquet, sit on flowers, fly feathers and get drunk on the moon. Without a good hymn, why open your arms? If you don't follow this poem, you will be fined the number of drinks in the shrine.
