Dreams, everyone can do, in fact, most of them have no practical significance, so don't care at all. Chinese and foreign views on dreams are actually different. For example, the Greek philosopher Plato once said, "Good people dream and bad people do evil." On the other hand, China's ancestors believed that no one had a dream. In other words, Westerners think that good people can dream, while China thinks that saints don't dream. After all, saints don't dream, because they have no delusions. But according to modern medical research, everyone dreams, so both sides' views are incorrect.
There are many kinds of dreams, at least China divided them into many kinds, and this habit has existed since ancient times. For example, Zhou Li Chun Guan clearly put forward six big dreams: positive dreams, nightmare dreams, sleeping dreams, happy dreams and fearful dreams; In the Ming Dynasty, Chen Shiyuan's Dream Theory is a collection of predecessors' masterpieces, which divides dreams into nine types: the dream of prosperity, the dream of qi deficiency, the dream of evil, the dream of stagnation, the dream of overflowing emotions, the dream of straight leaves, the dream of concreteness, the dream of anti-polarity, and the dream of evil spirits, which greatly deepens the classification of dreams. In fact, among China's ancient books, there are many books about dreams, the most famous of which is Duke of Zhou.
According to ancient records, dreaming that you have caught a fish usually means that you will have good luck, seize an opportunity or get unexpected gains in the near future. But it depends on the specific situation. If you catch fish in the water in your dream, because the water is generally represented by divinatory symbols in ancient times, and the ridge represents dangerous land without real soil, the whole dream becomes the consciousness of winning in danger or treasure hunting in danger, which means that there will be opportunities to win in danger in the near future. If a group of fish catches only one fish, it generally means that there are many opportunities or many rewards, but in fact they get very little. However, they didn't return empty-handed, which is still something to celebrate.
In short, dreams are natural phenomena, which everyone has, have no practical significance, and there is no so-called "catastrophe". If dreams can predict "catastrophe", will anyone commit crimes? Obviously, this is illogical.
