Floating in mid-air like a god, everything under the white mist appeared in front of his eyes, Wu Ling didn't do anything, just quietly watched everything below.

Taking the Dream Stone out of his pocket, looking at the stone that had regained its calm, Wu Ling was even more strange: "When did the Dream Stone have such a huge ability!" ”

For example, he has studied Dream Stone, without the replenishment of energy, the range covered is only one person at most, and even if it is supplemented with his energy, it can only cover a range of a few meters, and it is impossible to cover all people.

And now, Rumengshi has really done this.

"Nothing is impossible, boy, I just said, this time, you're in trouble!" Just when Wu Ling was strange, a voice suddenly sounded beside him.

Before he turned his head, a strong aroma of wine came, and Wu Ling knew who the person who suddenly appeared was.

"Since the seniors knew, why didn't you remind me just now?" Wu Ling didn't turn around, lowered his head, and said everything under his feet.

"Don't call me senior, we're really not a profession!" Hearing Wu Ling's salutation, the old man waved his hand and said.

"Then, uncle, do you want to help me solve my confusion a little!" Turning around and looking at the old man who was drinking in front of him, Wu Ling said directly.

"It's not impossible, but I don't like you here, it's too high, come with me!" Looking at this cloud-like space, the old man waved his hand directly and disappeared in place.

Reappeared, and the two of them were in the familiar carriage again.

A middle-aged man with glasses asleep on the upper floor, a girl reading a book on the side, and an old man sitting on the top bunk drinking, it seems that everything has returned to its original state.

"Uncle likes this place?" At this time, it was impossible for Wu Ling not to know that the old man in front of him was indeed not an ordinary person. Of course, this guess was not too out of line, and at the beginning, he didn't see that the old man was ordinary.

"I don't like it here, it......'s too crowded," the old man winked at Wu Ling and said.

Wu Ling fell silent, he didn't like to ask out loud.

"You kid don't follow the script, shouldn't you ask why? And then I'll tell you, we're on the train right now, so this is the place to stay now, whether I like it or not, at this stage, I'm only here! The old man couldn't help but be a little angry when he saw that Wu Ling didn't react, and he blew his beard and glared at him.

"Uncle, didn't you say it all!" Wu Ling smiled slightly and said.

He admits that what the old man said made a lot of sense. It is impossible to live according to your own wishes in life, there will always be ups and downs, whether you like it or not, he will appear. When that time comes, all I can do seems to be to accept, just like the train now. A lot of people don't like to take the train, but they have to squeeze in here because they have to go this part of the way to get where they want to go.

Dreaming, living, and surviving are the same.

"Forget it, it's really boring to talk to you kid, let's get straight to the point!" After being in contact with Wu Ling for a period of time, the old man also knew the thoughts of the young man in front of him, so he didn't want to continue to laugh, but directly changed the topic back.

"I want to hear about it!" Wu Ling really didn't know about the current situation, so he naturally wouldn't miss the old man's explanation.

"This is the dream space......" the old man took a sip of wine and said directly.

"I know!" Wu Ling said with certainty that the moment the dream stone glowed, he knew that all the people had come to the dream realm. He is not alone, because of the dream stone, so he can check everyone's dreams.

Just like just now, thinking of this, he looked at the uncle with glasses on the top bunk, and everything that happened just now was the uncle's dream.

"It's weird you know!" Hearing Wu Ling say so surely, the old man not only did not praise him, but rolled his eyes and said directly.

Seeing that Wu Ling seemed to be about to refute, the old man couldn't help but sit up, looked at Wu Ling, and asked directly: "Since you know, can you tell me, what is a dream?" ”

What is a dream?

Dream is a kind of imagery language. Zhuangzi. The Theory of Things" cloud: "And there is a great awakening, and then I know that it is a big dream." "These imagery range from the ordinary to the surreal; In fact, dreams often inspire art and other things, and the German chemist Kekule claimed to have dreamed of a snake devouring its own tail and realized the molecular structure of the benzene ring. Dreams can take the form of nightmares that wake people up and spring dreams that may accompany them.

The vast majority of scientists believe that all humans dream and have the same frequency every time they sleep. Therefore, if a person feels that they are not dreaming or that they only have one dream in one night, it is because their memory of those dreams has disappeared. This "amnestic" usually occurs when a person naturally and gently passes through the REM sleep phase and into a waking state. If a person is woken up directly from REM sleep, for example, by an alarm clock, they are more likely to remember the REM dream.

True dreaming has only been directly confirmed in humans, although many believe that dreaming can happen to other animals as well. Animals have been identified with REM sleep, but their subjective experience is difficult to determine. The animal that has the longest REM sleep period on average is the pangolin. Mammals may be the only, or at least the most frequent dreamers in nature, because of their sleep patterns.

Some people also think that the above explanation of dreams is unscientific, and that dreams are just a kind of mental activity when people are sleeping, and the mental activities in dreams are the same as the mental activities when people are awake, which are the reflections of objective things in the human brain. Bizarre dreams in dreams are caused by the illusion of stimuli of various objective things when the brain is unconscious during sleep. For example, the palpitations that seem to be being chased when a person is awake and tachycardia become a bizarre and fearful nightmare of being chased by others in a dream, and the palpitations caused by a person's awake slow heartbeat or premature beats become a bizarre and fearful nightmare of people hanging in the air and falling in a dream. In dreams, I can often feel some slight physiological symptoms that are not easy to feel when people are awake, which are caused by the relatively small stimulation of various objective things from the outside world and the relatively strong stimulation of various objective things from the body when people are sleeping.

This is just a general scientific explanation, from the psychological point of view, dreams are a window into the unconscious.

Psychologist Sigmund Freud believed that dreams are the satisfaction of the subconscious, and people can effectively suppress the subconscious in a waking state, so that those who violate moral customs cannot do whatever they want. But when people enter a state of sleep or relaxation, some ** will avoid the examination of the subconscious, secretly surface the conscious level, and express themselves in various images, which is the formation of dreams. Dreams are a substitute for human beings, and it is the main way to release repression, in the form of a fantasy, to experience the satisfaction of this coveted instinct. The ** fire hidden in Du Liniang's subconscious is suppressed and cannot be satisfied due to practical reasons, and the impulse and repression in the subconscious continue to struggle, forming a pair of contradictions.

And then form a kind of motivation. This motivation makes ** find another way or satisfaction, which is the dream.

Hao Bin, a well-known psychologist, believes that dreams are the manifestation of psychological conflicts in some cases. Mr. Hao Bin elaborated in his book "Hypnosis and Psychological Pressure Release": "There will be various feelings such as ** and emotions in dreams, although these are generated by your nervous system, but they do not fully represent you, and it cannot be said that the needs that appear in dreams are your essence. Many times the needs of the rational and the emotional needs are contradictory, they exist in your consciousness, and they fight with each other throughout your life. The conflict between these needs can leave you at a loss and lead to psychological disorders. However, if you have strong enough ego functions to reconcile these conflicts, they will make you grow better. In fact, this is one of the main purposes for many people to accept dream interpretation, hypnosis and other technical means for psychotherapy to achieve personal growth. ”

There are also psychologists who believe that human dreaming is a rehearsal of how to deal with a dangerous situation in a virtual environment. Nightmares, in particular, are 300 to 1,000 nightmares a year. It is in the nightmare that humans train for safety.

These are just some of the explanations of Western science, and there is also a very clear explanation of dreams in terms of liking.

According to TCM, a person's mental state (i.e. mental function) is made up of five parts. These five parts are stored in the five internal organs, also known as the "five aspirations". Su Wen. The Xuanming Five Qi Chapter says: "The five organs are hidden, the heart is hidden by the spirit, the lungs are hidden by the soul, the liver is hidden by the soul, the spleen is hidden by the will, and the kidneys are hidden by the five organs." "The Five Aspirations of the Dirty Elephant is the theoretical basis of dream interpretation in traditional Chinese medicine, and the five aspirations of the Dirty Elephant can explain dreams, and the main point is that the changes in the Five Aspirations are the internal causes of dreaming. The seven emotions, sickness, and internal and external stimuli are the inducing factors of dreams.

Seven Feelings. People have seven emotions: joy, anger, worry, sorrow, fear and panic, which are normal psychological activities of human beings. The seven emotions have a great impact on the balance of yin and yang, the flow of qi and blood, the function of the internal organs, and the smoothness of the meridians. Traditional Chinese medicine believes that the seven emotional processes of joy, anger, worry, thought, sadness, fear, and surprise summarize the main psychological activities of people. They are like the "five aspirations", which belong to the heart, liver, spleen, lungs, and kidneys, which are the emotional manifestations of the five internal organs. The imbalance of yin and yang in the viscera and the reversal of qi and organs can be manifested as changes and abnormalities in the seven emotions. In the same way, the changes and abnormalities of the seven emotions will inevitably cause the imbalance of yin and yang, the disorder of qi and blood, and the detachment of the five wills of the internal organs, and even directly damage the internal organs and the internal organs to which they belong. Normally, dreams are not caused, but strong mood swings can lead to dreaming. Among the above seven emotions, especially thoughts, worries, shocks, and fears lead to many dreams, so there is an ancient saying that "there are thoughts and dreams at night".

Disease, external factors, including normal environmental stimuli and pathogenic factors, invade the inside of the human body from outside the body, and do not belong to the corresponding viscera, but march all over the body with the operation of the qi of the camp and guard, resulting in the situation that the five wills are out of place and the soul is flying, and people are not at peace in their sleep and produce dreams.

In addition to the six silver qi, all factors that can cause disease in the human body, such as phlegm and dampness, blood stasis, plague, room labor, diet, trauma, insect accumulation, etc., may affect the yin and yang qi and blood of the viscera, thus inducing dreams.

In vitro and in vivo stimulation in vivo and in vivo stimulation include a wide range of aspects, such as seasonal exchange, climate, hot and cold, sound, smell, geographical location, sleeping position, etc.; Internal environmental stimuli include hunger, retention of urine and urine, thirst, dry throat, sweating, spermatozoa, menstruation, etc. External stimuli include seasonal and climatic factors, as well as stimuli for the body during sleep. For example, the weather is cold, and there are many sad and bitter dreams; In windy weather, you will dream of flying. Physical stimuli, such as falling asleep with something in your mouth, you will dream that you want to speak and cannot make a sound; Sleeping in clothes and trousers, sometimes dreaming of snakes; Ladies curl their hair with a curling iron before going to bed, and sometimes dream of their hair hanging from tree branches. Some dreams are not caused by physical and psychological factors, but by factors that appear in the sleep environment to introduce people to different dream environments, and the content of the dream is related to the stimuli felt by the sensory organs during sleep. When sleeping, stimuli from the body or outside the body are transmitted to the central nervous system, and they are often mistakenly felt, which does not correspond to the actual situation, and the illusion is first imagined as a dream. Like the sound of the whistling wind and the ticking of the rain, we will have the dream of "walking in the rain".

It can be seen from this that people's seven emotions, diseases, and internal and external stimuli can all induce dreams, which are the triggers of dreams. At the same time, it affects the generation of dream content to a certain extent. Modern medicine believes that dreams are caused by various internal and external stimuli acting on specific cortices of the brain during sleep, including the original traces of excitement remaining in the brain. Various stimuli, psychological, physiological, pathological, and environmental factors can influence the formation of dreams. Such as hunger, defecation, pain, lack of oxygen, parasitic activity, and mental and emotional activity.

Sleep is a process that alternates between slow-wave and fast-wave phases. Dreams mainly occur during fast-wave sleep, and some of the excitatory foci in the cerebral cortex are still active, but because the connection between these excited brain cell groups can no longer be carried out normally, the content of the dream is often bizarre.

It was found that those who were in the slow-wave sleep phase said that they were "not dreaming", and 85% of the fast-wave sleepers said that they were "dreaming" and were able to recall the dream they dreamed at that time. Awakening from fast-wave sleep can clearly recall dreams, especially 20 minutes after entering fast-wave sleep, the rate of remembering dreams is as high as 94%. Dreams are a reflection of this state of excitement in the human body itself.

Whether it is the scientific view of the West or the Chinese view of the East, it seems that they can explain this question of the old man, but now that there are supernatural beings, is this explanation still the answer to the question? (To be continued.) )
