Let me tell you a story. Once upon a time, a scholar had a dream on the first night when he went to Beijing to take an exam. The dream is like this. The first one is dreaming of wearing this raincoat and carrying this umbrella in rainy days. The second is to plant cabbage on the wall, and the third is to sleep in a bed with your own woman or back to back. The scholar doesn't understand how to find a dream in the morning. When the dream interpreter told him, he explained the dream. It turns out that it is unnecessary to put on this raincoat and play this umbrella in rainy days. Planting cabbage on the top of the wall is white. Sleeping in the same bed with your own woman or back to back means you're finished. The scholar was very sad to hear that. Later, I met a friend at home. His friend asked you why you didn't take the exam. The scholar said that everything was like his friend's. His friend had a dream for him, so he put on this raincoat and played this umbrella in rainy days to prepare. He solved the problem of planting cabbage on the top of the wall and entering high school. Sleeping in a bed with your own woman or back to back means it's time for you to turn over. Hearing this, the scholar's spirit increased greatly, so he went to the exam and took it.
Therefore, people should not think about unnecessary things just by dreaming, it is just unnecessary.
