Duke Zhou dreamed that there was a grass wall beside me? I dreamed that there were grass walls all around, and I stood in the middle. The grass wall around is one meter.

It's like sitting in a sleeping city. There are walls all around, only one meter high, but there is an exit. The grass on the wall means that you have no freedom. You long for extreme freedom, and even grass appears in your dreams. Even if you are tied down, you long for freedom. You are living a very comfortable life now, but you are eager to go out and see the outside world. You think the outside world is grass and freedom, so the wall is only one meter high, but it can protect you. You want to go, but you are afraid of the outside world. Are you going to leave home to study or work? Or get married or something?
