I had two dreams recently. Duke Zhou said that there were difficulties to stop success, and that disaster was coming. What is this? What should I do?

There's nothing to say, only that you are superstitious and ignorant. Duke Zhou, that's just an unreliable fabrication with no scientific basis. Of course, if you choose to believe, you can only be blinded and misled by your own ignorance. In fact, dreams are an unnecessary combination of your memento mori, which may be related to what you think, see and hear, and are not a sign of your future. You should improve your personal cognition and knowledge reserve, and don't be blind and ignorant.
