What does the duke of Zhou mean by fighting with his dead lover in his dream?

In my dream, I dreamed of fighting with my dead lover: I went out to play and didn't want to be nagged all the way-my dog fought with my neighbor again ... I was so bored that my long-awaited rest was ruined. Fortunately, I met another handsome girl and had a good chat. It's a little comforting, but be careful. It's dangerous to have two feet on both sides.
