I was fishing on the Bixi River in my spare time, and suddenly I was riding a boat and dreaming of the sun. What psychology does the poet express?

I was fishing on the Bixi River in my spare time, and suddenly I was riding a boat and dreaming of the sun. "The poet was in a daze, and suddenly thought of two people who had a difficult time in politics at first, but finally made great achievements: one was Lu Shang, who met King Wen when he was fishing in Feng River at the age of ninety; the other was Yi Yin Before being hired by Tang, he dreamed that he was sailing around the sun and the moon in a boat. The allusions of "fishing in the blue stream" and "dreaming about the sun in a boat" expressed that one day he could be trusted and used by the ruler and build a great cause like the ancients.
