[Dreaming of a well] Ancient dreamers had different judgments about different situations of dreaming of a well. "Dunhuang suicide note, a new collection of Zhou Gong's letters": "Those who dream of crossing the well will gain far-reaching trust; He who dreams of a boiling well is rich; People who dream of looking at the well will get an express letter; I dreamed that I was lying in a well and was a big murderer.
