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; Chen Shiyuan in Ming Dynasty, who is a master of dream theory in past dynasties, divided dreams into nine types: dreams of prosperity, dreams of qi deficiency, dreams of evil, dreams of stagnation, dreams of overflowing emotions, dreams of straight leaves, dreams of figuration, dreams of anti-polarity and dreams of fierce demons, which greatly deepened 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 water is generally represented by divinatory symbols in ancient times, and ridges represent 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.
