You stand on the bridge and watch the scenery.
The landscape observer is watching you upstairs.
The bright moon decorated your window,
You decorated other people's dreams.
This poem is "Writing an Instantaneous Artistic Conception". "I like to think that people and things in the world are closely related, interdependent and interactive. People ('you') can look at the scenery and decorate it intentionally or unintentionally. People ('you') can see the bright moon decorating their windows, or they may become decorations in other people's dreams consciously or unconsciously. "It can be seen that the poet intends to express the complementary relationship between people and things.
