Dream of a man carrying a pole.

Dream, a beautiful and ethereal physiological phenomenon, has given people a lot of joy and hope throughout the ages, but it has also brought people a lot of confusion and depression. It is like a white cloud floating slowly on the horizon, which paints people's lives with magnificent colors. However, in a blink of an eye, the white clouds turned into shadows, giving people anxiety and sadness. It's confusing, mysterious and elusive. However, it is so lively that it brings joy and hope to people. Since ancient times, many literati around the world have eulogized and praised it, leaving many beautiful and moving descriptions, and many wonderful and magical legends about it have also been circulated on the earth. Ancient emperors used it to predict the rise and fall of the country, the quality of the country and their own destiny; The Lebanese people also associate the happiness of the world with disaster. There are countless stories about dreams. For example, the well-known story "Huanglong Dream" is still a household name, and it is well known to all women and children. The dream pen gives birth to flowers is even more interesting, telling the story of Li Bai, a great poet in the Tang Dynasty. According to legend, when Li Bai was young, his poems were not outstanding. Once he dreamed that all the pens on the table were in bloom, and his literary thinking improved so much that he reached the point of "one hundred poems about fighting wine". It is also said that in the Northern and Southern Dynasties, Jiang Yan, a scholar, had a five-color pen in his dream. Since then, his literary thought has made great progress and gained great reputation. A few years later, he dreamed of returning the pen to the author, and his literary thinking dropped sharply, leaving no good works to tell. This magical legend seems absurd and incredible now, but for thousands of years, this legend has painted a mysterious and beautiful color to dreams, which has aroused many people's deep thoughts and prayers. People are curious and pious about dreams, and they also have many reverie. Try to unveil the mystery. As a result, many scientists have spent their whole lives on it, and many scientists are still exploring it. What is a dream and how to define it? Judging from the relevant information, people's opinions are still divergent. Let's take a look at the ancient and modern Chinese and foreign interpretations of dreams.

The Mohist book says: "Dream, lie down and take it for granted". It is a phenomenon to think that dreams are what people think they see and that something happens during sleep.

In Shuo Wen Jie Zi, it is said: "The dreamer, the awakened one, feels also". Think that dreams are a feeling in sleep.

Plato, an ancient Greek philosopher, thought that "dreams are the continuation of human daily life". He also believes that "dreams are the source of creation".

Psychoanalyst Freud said in the book Analysis of Dreams: "Dream is the satisfaction of a repressed desire through deformation".

F. Thompson said in "Physiological Psychology": "Dreams are normal mental disorders, and dreaming makes each of us go crazy quietly and safely every night of our lives."

According to Mr. Wang Jisheng, "Dream is a psychological phenomenon. Conscious and unconscious information is stored in the brain and combined in some way during sleep".

Modern Chinese Dictionary explains: "Dream is an apparent activity in the brain caused by local substances in the brain not completely stopping during sleep."

The Concise Dictionary of Biology explains: "Dream is a physiological phenomenon in the process of sleep, which is characterized by complex, fragmented and sometimes chaotic mental activities".

The Dictionary of Modern Science and Technology explains: "Dream is a series of involuntary visual, auditory and kinesthetic representations, as well as emotional and thinking activities that occur in consciousness during sleep or similar sleep state".

A Concise Dictionary of Psychology explains: "Dream is a passive and involuntary imagination, which is carried out naturally without the adjustment function of the second information system".

The Concise Encyclopedia Britannica explains: "Dreams are activities that appear in the brain after falling asleep. There are different understandings of the essence of dreams, or that dreams are a reflection of reality, a source of foresight and a spiritual feeling to get rid of illness, or that dreams are also a state of awakening, or that dreams are regarded as a subconscious activity ... ".

The book "Interpretation and Treatment of Dreams by Traditional Chinese Medicine" holds that dreams are caused by internal and external stimuli, which occur during sleep and are difficult to control.

Although there are different opinions about the definition of dreams among researchers who are committed to dreams at home and abroad, it is still difficult to give a satisfactory definition of "dream". We believe that dream is a kind of mental activity caused by the fact that the local brain tissue (cerebral cortex) does not completely stop exciting activities when people sleep. The content of a person's dream is related to the impression of life left in his conscious mind when he is awake, but in dreams, the impression of life often becomes chaotic, so the content of dreams always presents a chaotic and illusory state, which is expressed in the form of imagination or illusion.

So it's okay! ! !
