Discuss why people dream

Why people will dream sleep, the widely inhibit nerve cells, but the inhibition process is incomplete.As a result, some of the cerebral cortex nerve is still in the excited state, resulting in a dream.Visible, the dream is under the condition of a few cell activity in the brain cortex.If a handful of cell activity, losing the arousal of the whole control and regulation of the cerebral cortex, memory fragments unbridled ground to life, so people can produce strange dream.If during sleep, the minority in the excited state of the cell is certain cerebral cortex related to language or motor nerve cells, so, there will be people usually see it say talk in a dream, wait for a phenomenon.Dream is in one's sleep, especially the results of the neural activity during rem sleep, the dream is also a kind of psychological activity, is the result of a certain level of consciousness activity.According to Freud, the person's unconscious contains a large number of concepts, ideas, desire and impulse, etc., these ideas and thoughts, because with the social ethical conflicts and suppressed in the unconscious, the individual can't detect.Freud called the person's psychology as an iceberg, the consciousness of people is a corner of the iceberg above the water, the unconscious is the part under the water.Although the content of the human consciousness cannot be realized, but can leak out through this or that kind of way, one of the important ways is a dream.Anyway, the dream is always caused by some nerve cells in the activities of some of the stimulus as a result, but it cannot be clearly aware of, also can't control myself.There is a so-called with foresight dream,, for example, you dream of his legBitten by a dogLegs are really long tumour in a few days, and how to explain this?The lack of scientific knowledge people will think that is god appeared to you, indicate your leg is broken, this is caused by internal stimulation.Tumor grows on the leg, it is not a day can, just began to stimulate the weak, not reached

Threshold of feeling, so it is difficult to detect, and while you are awake, people cared more about the outside world, the micro: weak inner world are harder to detect, but when people sleep most of the nerve cells in the inhibition of state, the stimulus was relatively strong, and make you have some awareness and can't control, so they may be linked with relevant things unconsciously constitutes the dream, such as dream of leg was bitten by a dog, or his leg riding, etc.This is why a dream has a certain predictability.

Why people dream?

Dream is a person in a normal physiological phenomenon in the process of sleep.Everyone just dreaming more and less;Some wake up fresh, some vague or perceptible.Those who assert that oneself never had a dream, just forgot.Therefore, for dreams don't have to make a fuss.

Due to people in dreams in the right hemisphere activity predominates, while after awakening in the left cerebral hemisphere dominant, in the body's 24-hour circadian activity process, waking and dream appear alternately, can achieve neuromodulation and the dynamic balance of mental activities.Therefore, the dream is a way to coordinate balance of human mental world, especially to the person's attention, emotional and cognitive activities has the obvious effect.

General sense of the dream will not result in a physical discomfort, mental or physical burden, without too much, but some people think dream affects normal sleep and waking mind giddy, spirit trance, body tired weakness, the dream is still a long tangles in the brain, feeling serious affect sleep, this is not a dream, but a symptom of insomnia, insomnia is commonly associated with pathologic much dream, which is due to insomnia caused by a lack of sleep and sleep patterns caused broken tired feeling, in fact it is not a tired feeling from a dream.

Greedily munching on fruit in the dream, the dream suddenly feel nausea, vomiting, dreamed of healthy teeth, suddenly fell to the groundBeing chasedPanting, run...Believe that everyone has a similar situation in the dream, but everyone psychological reaction for dreaming, some people, some people are worried to psychological doctor for help.Dream is suggesting some psychosomatic disease?Beijing university psychology professor Shen Zheng introduction, modern psychology studies have shown that under the condition of throw human factors interfere with normal sleep, if a person in a recent period of time often do is roughly the same dream, can be seen as a warning on the psychosomatic health of nervous system, must attach importance to it.

Psychological experts in relation to the dream, you must put aside human factors.Which belongs to the human factors?Psychologist, he says, has done the experiment, the sleeping eyes spray, 1 minutes to wake it up, wake up all people saidDream of the heavy rainOr intoThe seaIn the dream associated with water, etc.And if at the both legs of the event, the dream is mostly related to sports, some people dream about being chased is run, some people dream about fall into the abyss.The two experiments suggested that dream and sleep to environmental factors.In addition, the dream also influenced by sleeping posture, sleep position of people also can produce stimulation to dream, like a leg down the other leg, will dream about being chased is run, pillow oppression jaw will beDream away teethAnd so on.At the same time, the bedroom environment also can affect dreams, such as bedroom near a highway or train, will hear strange ring in a dream, just before bed, eat very uncomfortable, will feel nausea in the dream.

After exclusion of the environmental factors that affect sleep, for a period of time often do the same or similar dreams may indicate potential problems.Shen Zheng, says professor carefully think about it, the following scenario do you often dream, dream strange ring, predict auditory system might have potential disease;Dream of eating, feel nausea, vomiting, may indicate the stomach have potential diseases;Dream of toothTeeth, do the same for several daysOff teethDreams are related to oral exercise and gastrointestinal function, prompt the existence of the digestive system and respiratory system disease.A dream Shouting, also called a nightmare, the person is in danger if a dream, but if someone chasing run, when people will be very panic, often characterized by Shouting.If a person often nightmare, is due to excessive excited state of the brain, mind frequent activities and get proper rest.Then you need to use some inhibitor drugs into the brain during sleep, should have a rest, can work better in the daytime.

Although dreams can remind health, but not as long as the dream, it means what disease, it is unscientific.Shen Zheng professor reminds, excluding environmental and psychological factors, appeared again and again in the dream for a long time, you will need to be vigilant, in a timely manner to the hospital check to rule out the possibility of the disease, also check the sleep at the same time, and through medication to improve sleep, make such dreams no longer appear.

The benefits of a dream

1.Adjust the psychological

We know that if they did the night before dream, feel energetic of the next day, the mood is very comfortable.But if was a nightmare, the next day, the mood also not happy, can feel didn't sleep well, anxiety, irritability, love lost his temper, can't do the static heart.Visible dream is kept in good state of mind of a necessary link.

From the perspective of psychology of psychoanalysis, the meaning of the dream is to through the satisfaction of desire.Whether you're a man of noble or humble people, our deep heart, too much was collected are willing or able to speak and a desire to be unwilling or unable to speak.These almost endless desire, many in real life can't instant gratification or not at all satisfied.Not or cannot obtain the desire to meet in real life, it can get psychological meet in a dream, adjust the psychological balance.

If there is no dream, so big and small desire will make us unable to sleep.Even if we sometimes nervous anxiety in a dream, also can let the dream and sleep.

2,Remove fatigue, recuperation body

Fatigue is man no matter in physical activity and mental activity, the depletion of energy, energy is mainly depends on the blood supply of the braingrapesSugar.Physical and mental activity requires a lot of glucose, if the blood supply of glucose still doesn't satisfy the need of it, this time it will use the reserve of the body.Using the body reserves of the process can produce a kind of lactic acid.

Lactic acid accumulation, is a kind of physiological, biochemical fatigue performance.Sleep can relieve the fatigue.Sleeping, all the activities of people stopped, muscle, it reduces the consumption, to save energy, the temperature is reduced.

People at the time of sleep, and a function, is the synthesis of new proteins.New protein of human need, were mostly synthetic while sleeping.So sleep is essential to remove fatigue and recuperation body.

3,Arrange information, bring enlightenment

We experience a lot of things during the day, our brains to record all the time, to constantly monitor, all the records of what's going on around you.

Whether you consciously, or unconsciously, especially visual very informative, as long as you eyes swept away, all the stimulus will run into your brain.When you sleep, the brain will replay, playback, side, and then according to different content, different functional circuits, respectively, put it on the brain.

In addition, the brain in the night and the function of learning.For example a mystery is very famous in the west, detective mystery by day, how can't think of this case happened.He ended up in the night dream, the dream come out what is going on, according to his dream, the next day broke the case.Like this in the night of sleep, dreams sometimes brings insight and sometimes leads to innovation.

4,Dream can help brain function

Dream can make the inside of the brain produces extremely active chemical reaction, make the brain cells of protein synthesis and update the peak, and quickly through the blood with oxygen and nutrients, and the waste away, which makes itself cannot update brain cells quickly update their protein composition, to prepare for activities in future.Therefore, on one hand, dreaming helps the brain function.

Part of the brain cells in the waking state doesn't work, but when people sleep, these cell is in "exercises" its function, and thus formed the dream.Dream to painful or happy memories, dreams to exercise the function of brain, dreams can guide you to change your life, and sometimes also can partly solve the conflicts of waking will make your life more fulfilling.
