Why do you have pleasant dreams and nightmares

Why do you have pleasant dreams and nightmares

After unveiling the mystery of dreams, we will discuss why people dream, and why some dreams are melancholy, some dreams are dangerous, some dreams are afraid, and some dreams are happy?

Scientific research shows that dreams are an organic combination of some abstract things, and there are many factors causing it, mainly the following:

1. Brain activity The electrical activity in the brain during dreaming is obvious. The transfer of energy and images in the brain is guided by a network of nerve cells, and the basic material of the brain constitutes the electronic wave network, which is composed of capacitors (electrical storage) and transistors (electrical channels).

During sleep, physical activity is greatly reduced, the breathing rate is reduced to half of the awake rate, the heartbeat activity rate is also reduced to 40 to 70 percent of the awake rate, and the metabolism and blood pressure are also greatly decreased. But according to Harvard Medical School

Scientists say that even during deep sleep the activity of electrical nerve cells in the brain is reduced by only 5 to 10 percent!

Even though the electrical nerve cells were only reduced by 5 to 10 percent, certain parts of the brain were more affected. The areas most affected are those that regulate attention, learning, information assembly and memory. The temporal activity of these parts decreased by 50 percent during sleep, but ceased completely during the rapid eye movement phase.

The learning, memory and attention centers deep in the cerebral cortex are actively working, classifying the information received by the brain as important or irrelevant, and allocating this information to memory resources accordingly.

The amount of information entering the brain often exceeds our brain's conscious ability to process each individual piece of information separately. Memory resources are then allocated according to the urgency of a given moment. At any given moment, the brain has the ability to retrieve relevant memories in order to judge the importance of the situation.

2. Recombination of Reality One of the most common features of dreams is that they recombine reality to create a grotesque reality. In a single, coherent dream, your brain might conjure up this scenario: two of your acquaintances become marriage partners, and they are on a secret lunar trip to a foreign country, even though they are both your acquaintances

This is a stranger. There may be some reason why it all ties together, but clearly that reason is not obvious.

Because a dream is like a Mosaic floor, you should look at the picture in the dream on a larger scale: why do seemingly unrelated things appear in the same dream? Maybe their co-existence in dreams isn't weird after all.

3. Mental anxiety During stressful sleep, although there is no proven link between anxiety caused by a highly stressful lifestyle and sleep disruption; But what is certain is that the anxiety that people face when they are awake certainly manages to find its way into their sleep. In fact, most of your dreams include images and emotions designed to minimize your waking anxiety.

However, it is not easy to predict who will have excessive dream anxiety. You might expect an obviously agitated person to have more nightmares, but this has not been proven, and it is likely that the opposite is true. In fact, some of the people who are more likely to experience stressful dreams tend to be those who have hidden inner anxieties during waking hours, and these people tend to have personalities that are overly sensitive to intrusions and threats. They are seen as people with relatively fragile personalities. You will often meet people who, on the surface, are gentle and calm, but they are the most restless people in their dreams.

In addition to the mental reality of the dream, there may also be a physical reality, and it is this physical reality that causes the physical response of the sleeping body. For example, people often dream that while they are lying in bed, something comes up to them and squeezes their arms. Some people say it's because they feel a certain smell in their sleep, although this is very rare. Others say the pain is a part of their sleep. These feelings often occur in the early stages of the sleep state.

Often the physical sensations people experience while dreaming do not enter into their waking lives. For example, if you dream of falling out of a tree and breaking your leg, you experience a painful sensation in your dream; However, it is unlikely that you will feel any lingering pain in your legs after waking up.

In addition to the organic combination of abstract things, dreaming is also related to the emotional changes of the dreamer. Because people have seven feelings and six desires in knowing things around them and interacting with others, they often show corresponding feelings, and corresponding feelings will trigger corresponding dreams.

About this, our country has noticed it for a long time. The famous philosopher Wang Chong of the Han Dynasty, he was on the spiritual psychology of dreams

In the analysis of the reasons, it is believed that dreaming at night is not caused by ghosts and gods, but is transformed by psychological activities during the day. Because people often miss something when they wake up, full of some kind of imagination or hope, they will dream of what they miss when they sleep, or things in their imagination, Wang Chong summarized these as 'fine thoughts and thoughts' to dream. He wrote in his book on the Rule of Ghosts:

'The thoughts of the husband are in the eyes, in the mouth, or in the ear. Leak to the eye, see its shape; Leak in the ear, hear its sound; Let it out, let it out. I see ghosts in the day and smell dreams when I sleep at night. I sleep alone in an empty room. If I am afraid, I dream that my wife is crying according to her body.'

We can know from his dream examples that the so-called fine thoughts include various emotional factors such as happiness, sorrow, sorrow, and panic. Read is missing, 'said the text' said: 'read, often think also.' Fine for focus, fine thinking, that is, miss very fine, very deep, very special, deeply miss. Thinking, on the one hand, means always thinking about a certain thing, a certain situation, or a certain emotion is always bothering you; On the other hand, it also means that some idea, imagination, or emotional feeling is stored in memory

We can experience that dreams are sometimes related to the current day or recent changes in mood, and sometimes to changes in mood long ago

This is no doubt due to the fact that past emotional changes are stored in memory.

Emotional changes cause dreams, which can be caused by normal emotional changes or by excessive emotional changes. In addition, excessive emotional changes are more likely to cause dreams than normal emotional changes. Therefore, Chen Shiyuan said in discussing the dream of 'overflow of emotion' : 'Too much happiness will open the dream, too much anger will close the dream, too much fear will hide the dream, too much sorrow will dream of anger, too much sorrow will dream of salvation, too much anger will dream of abuse, too much fright will dream of madness.' The overflow of this kind of dream can be inferred.' The so-called 'overflow' is excessive emotional change. Chen Shiyuan divided the dream into qi, qi deficiency, body stagnation, emotion overflow and other categories, and named the dream caused by emotional changes as 'emotion overflow hair', the mood changes vary, and the impact on the dream is also different. Joy is the desire of the heart, which is the emotional experience produced when a person pursues and achieves the desired purpose. When the joy mood fluctuates, you will feel happy, the whole body is comfortable, Qi-blood regulation, so the 'plain question? Lift pain' said: 'Happy Qi and Zhi Da, Ying Wei Tongli.' The feeling of joy can be seen not only in waking, but also in dreams, and sometimes the joy in dreams is caused by the feeling of happiness in waking, and is a continuation of the feeling of happiness in waking.

A happy dream can be either a happy dream or an opposite dream. Chen Shiyuan once cited dreams such as 'when there is a marriage Yan party, you dream of crying' and 'When you celebrate, you dream of Ma Tho murder suits' to illustrate that a happy mood and celebrating joy do not necessarily lead to joyful dreams; However, in most cases, the dream is because of joy, and the dream is mostly happy.

Dreams caused by anger are often repressed in the dream; Or to repress the object of their own can not be taken sober. Chen Shiyuan said in 'Dream Account' : 'Too much anger will shut the dream.' Happiness is the dream of flowers in full bloom, anger is the dream of flowers withered. In life, there are often such dream cases, when a person meets something in society that makes him angry and there is nothing he can do, he will take some measures in the dream.

Dreams are caused by worries, sometimes related to things that worry about. If there is a rich man surnamed Yin, rich and powerful, but a bed is 'dream of being a servant.' Move forward to work, all also do; The number of scolding sticks and tarts, all the same.' This may have something to do with his constant fear of losing his precious status. Sometimes you may dream of very satisfactory things, because people are disturbed, they want to go smoothly, this mood, often in the dream will be realized.

Dreams are caused by sadness, and sometimes dreams seem to be related to the cause of sadness. For example, a patient's son was in a car accident shortly after her husband died

When she died, she was very sad, depressed and confused, so that the spirit was depressed, silent, unable to sleep all night, and when she closed her eyes, she would dream of her lost husband and son. Chen Shiyuan believes that excessive sadness is dream rescue, which may be related to the dreamer's disillusionment, loss of confidence, and desire to be rescued by people.

Dreaming is caused by thought, and its dream image is often related to the content of thought. As the saying goes, 'think day, dream night.' Du Fu's famous sentence 'old friend into my dream, clear my face memory', 'three nights of frequent dream, love to see the meaning of the king', reflects Du Fu's missing feelings for his friend Li Bai. Thirsty dream of drinking water, hungry dream of eating, sick dream of seeing a doctor, prisoners dream of being released, although the dreams are different, but different with their own thoughts. Of course, the dream has uncanny, it is sometimes like a naughty elf, not all think to see in the dream, 'want to lean single pillow dream, dream and not light and do'. It can be seen that thinking of it as a dream can be manifested as a variety of dreams.

From fear to dream, it can be expressed as a dream of fear. Chen Shiyuan said in Dream Zhanyi, 'After fear, dream is hidden', which means that in dreams, it is expressed as hiding everywhere because of fear. Because the fear of damaging the kidney can affect the heart, it is often accompanied by palpitations and other diseases. For example, a patient, when taking a bus to work, the car hit a person, the person died on the spot, the patient felt very afraid, ever since

Often feel palpitations, legs are weak, afraid to take a car, sleep is not good, close my eyes to dream, and most of the dreams are very scary, so that often wake up from the dream, still feel throbbing after waking up.

By fright to dream, its dreams are mostly nightmares, and sometimes even make people afraid to fall asleep because of fear. This point can also be seen from Zheng Xuan's comments on nightmares in the Han Dynasty. A nightmare is a nightmare. Zheng Xuan said in the commentary: 'shocked and dreaming.' He annotated the six dreams of Zhou Li from the causes of dream formation, and he believed that the cause of nightmares was caused by consternation.

For example, a woman, postpartum more than 20 days, due to sudden shock at night, so lead to palpitation, dizziness and fatigue, hear a voice will be scared to wake up, cold sweat, difficult to sleep, drink a few pieces of calming tablets before barely falling asleep. Another example is a Mr., when helping a friend to sort out the items, suddenly frightened, resulting in trance, often sad crying, dizziness, chest tightness and palpitations. Many dreams at night, dreaming of mostly horrible things, she often woke up from the fright, so that a person did not dare to sleep. After nourishing the heart and calming the mind, clearing heat and eliminating phlegm agent is good. This suggests that fright can indeed cause dreaminess.

In short, there are many factors that cause dreams, and the dreams that cause depression, thrilling dreams, fearful dreams and happy dreams are nine out of ten related to your emotions and psychology.
