Duke Zhou dreamed that a sheep was bitten by a dog. He was a sheep. How to solve it?

Dreams gave our ancestors (and us today) a key to solving real-world problems. Barrett once cited an experiment by Stanford University psychologist William demont to support this theory. In 1970s, Dement asked hundreds of his undergraduates to do a series of challenging questions before going to bed, so that they could fall asleep with them. One of the topics is this: "There is an arrangement of infinite letters. The first few letters are O, T, T, F, F … Please find a simple rule to determine any letter and all letters. " The rule is that each letter is the first letter of its corresponding number. For example, if the next letter is the sixth, it is the initial letter "S" of the English "six" of the number 6. ) There is a student who thinks before going to bed. After falling asleep, he dreamed that I was walking in a gallery. I counted the photos hanging on the wall for no reason-one, two, three, four, five. But when I came to the sixth and seventh paintings, I found that they were torn from the frame! I stared at the empty picture frame and felt as if I had discovered something secret. Suddenly, I realized that the sixth and seventh gaps were the answer to that question. In addition, Barrett also cited other examples of giants from all walks of life who made breakthrough discoveries through dreaming. Among them, German chemist Auguste Kekulai's famous dream about a snake biting its tail led him to discover the cyclic structure of benzene molecules. It also includes Demitri Mendeleev's dream of putting chemical elements into the periodic table. In Barrett's view, such anecdotes and a large number of experimental findings show that brain regulation theory alone is not enough to explain the reasons for dreaming. She believes that at some point, "putting the problem to sleep first" may be much better than meditation. There is no answer to what a dream is. Personally, I think these mainstream evolutionary theories are correct to some extent, but unfortunately, none of them can explain the inexplicable phenomenon of "dream repetition". The so-called "recurring dreams" refer to those dreams that you have had over the past few years-just like a tape that has been stuck and played repeatedly (in recurring dreams, I always forget the schedule of high school and the arrangement of school lockers-although strangely, I don't feel any inconvenience). In a study published in Consciousness and Cognition in 2006, Sadra, Desjardins and Marcourt analyzed the contents of 222 repeated dreams-the "makers" of these dreams ranged in age from 18 to 8 1. In these dreams, "running away" and "chasing" are the most common themes (about 25.9%), followed by "accident" and "misfortune" (about 19.7%), "attack" and "violence" (about 19.0%), and ". Moreover, in almost all these repeated dreams, the dreamer will portray himself (rather than his relatives or strangers) as a person in danger, and they usually take some actions to get out of trouble, escape from danger or overcome threats.
