At night, I dreamed that I found a well in a field on the mountain and drew water. How did Duke Zhou understand it?

Found a well and got water.

So generally speaking, your dream is a good dream, which is a good sign. It means that you have to meet a noble person when you are away from home or in your career, just like a glass of water, which you can't get. It can help your noble person or friend. The mountain represents the peak of your career or study.
