Duke Zhou dreamed that he did not take a bath in the bathroom, but took a bath in a crowded place, and regretted it afterwards.

I don't know Duke Zhou very well. But according to Freud's theory, bathing or going to the toilet in a crowded place may be a reaction to the recent chaotic life and emotional disorder. It is also possible that privacy is spied on and people feel powerless because there is no privacy. As for the regret in the heart, we can take the former possibility, that is, the dreamer's regret for this chaotic life state.
