Why do dreams occur in the brain when I sleep?

I believe that everyone will dream more or less when they sleep, but dreams are always very different from reality, and sometimes there will be some "incredible" and very "bizarre" dreams, some dreams can make us feel refreshed, but some dreams make us very worried and afraid, so why do we sleep when the brain produces "dreams"? What does our brain produce when we dream?

In fact, for centuries people have been trying to figure out why our brains enter strange dream worlds every night. The interpretation of dreams was studied in the 17th century, when Austrian neurologists systematically studied dreams from a psychological point of view, and he believed that dreams are our repressed desires, and that our wishes that cannot be expressed openly in social situations are sometimes manifested in our dreams. In fact, dreams are the subconscious activity of our thoughts and desires, and then some scientists have also put forward different theories, although they believe that sleepwalking is the psychological root, but also believe that dreaming allows us to reflect on our waking selves.

We can think and solve some of the problems we encounter in dreams, when the time enters the 60s of the 20th century, people's research on dreams enters the field of biological experiments, when people shift from light sleep consciousness to deep sleep consciousness, the eyeballs will move rapidly, and when the eyes turn from deep sleep consciousness to light sleep consciousness, the eyes will stop moving, the deep stage of rapid eye movement is called rapid eye movement sleep, and the light sleep stage when the eyes are stationary is called non-rapid eye movement sleep. If people were awakened from REM sleep, 80% of them reported that they were dreaming.

In fact, the dreams we usually have are the subconscious activities that we produce when we are working and going to school, after all, there are many things that you can't do in public, and then you can easily achieve them in the dream, and you may even do something beyond your usual imagination. After all, your thinking and subconscious have been suppressed for a long time in life, and the dream will completely burst out, who knows that you will also dream of some things that you are afraid of or make yourself happy in the dream, these are just the non-stop activities of your brain.

Because when sleeping, the brain is not idle, and the cerebral cortex is still active, so various dreams appear.

Because the dream itself is caused by something that a person hears and comes into contact with in real life. So the brain appears that these are the signals that the brain is processing and storing daytime information.

Because the brain has a hippocampus that stores memories, and when it comes to sleep, it releases some memory fragments.

Why does my brain have messy dreams when I sleep? You may not believe the reason.

Why does the brain have messy dreams?

The production of dreams is closely related to the activity of the cerebral cortex. Studies have shown that neurons in the cerebral cortex are still active during sleep, but their excitability decreases, leading to some abnormal changes in the activity of the cerebral cortex. This change causes some dysregulation in the processing of information in the cerebral cortex, which leads to the production of dreams.

Neurotransmitters are substances that transmit information between neurons in the brain. Studies have shown that the amount of neurotransmitters secreted in the brain changes during sleep, and these changes are also related to the production of dreams. For example, a decrease in the secretion of serotonin can cause people to be prone to nightmares, while an increase in dopamine secretion can cause people to have pleasant dreams.

In summary, dream generation is a complex process that involves multiple factors such as the cerebral cortex, the subconscious, and neurotransmitters. Before a dream encounter, the brain is in a special state that is more likely to produce dreams than when you are awake. Therefore, dreaming while sleeping is a normal phenomenon that everyone experiences.

To sum up, the generation of dreamless spring is a complex process, involving multiple factors such as cerebral cortex, latent consciousness and neurotransmitters. When people dream, the brain is in a special state that is more likely to produce dreams than when they are awake. Therefore, dreaming while sleeping is a normal phenomenon that everyone experiences.

It is a physiological phenomenon that people can dream; The reality of dreams is true and false.

Dreaming is a normal physiological phenomenon during sleep. Everyone dreams, just more or less dreams. Some wake up with fresh memories, while others are vague or imperceptible.

Those who assert that they never had a dream, simply forget about it. The reason why people dream is because the process of human sleep consists of several stages. During light sleep, some brain cells are more active, and there are symptoms of dreaming.

People sleep deeply only 25% of the time, and the rest of the time they may dream. <>

There are many kinds of dreams. Some people will eat delicious things in their dreams, some people will dream that they are successful, and even have some strange and weird scenes in their dreams that they have never seen. Of course, sometimes I have special dreams that may be difficult for some people to say, but dreaming is completely normal.

In dreams, will we be like the out-of-body of the original god, as the ancient sages said, only our original god appears in a dimension that we never knew, a world determined by our personal likes and dislikes, a world completely dominated by us, everything is possible. The essential truth of all things will never change because of the denial of the overwhelming majority of people, nor will it change because of the approval of the majority of people. <>

In a sense, our human cognition doesn't change anything at all. Different people, different scenes, the world is different in everyone's eyes. Maybe everyone's dream world is real, just like Buddhism has clouds, a flower and a world, a leaf and a Buddha, you can't tell the truth from the false.

The universe is vast, we humans have only been born for millions of years, and the rapid development of modern science has lasted for hundreds of years. Our knowledge of the universe is very small, and the matter we can perceive is only 5% of the universe. Since we have such a shallow cognition, perhaps your dream is actually happening at an unknown interface.

Because dreams are equivalent to the simulator of the brain, and they are also generated by the brain when it organizes memories; The reality of these dreams is very weak.

Sometimes the brain is in a state of excitement when sleeping, so it is able to dream, and these dreams are not real.

Dreaming means that the sleep is relatively light and has not entered a deep sleep, so it will dream, but this kind of dream will almost forget when you wake up, and you will not remember what happened in the dream.

It means that the brain activity is very active, and the things that are done during the day are not solved, and the heart is thinking, so it will dream.

I think dreaming represents a person's imagination, because there is a saying that there is a thought in the day, and there is a dream in the night.

1 Dreaming is a small movie in which the brain is replaying a microcosm of your events that day or a long time ago, these things are stored in the brain, and these images are intertwined with today's events and yesterday's events, so many dreams feel strange.

It is impossible for 2 people to rest their brain cells when they sleep, and some cells do not rest and are more active, so they begin to reminisce - dreaming. So when dreaming, the body and brain are also rested. But frequent dreaming will affect the quality of sleep and affect rest.

Dreaming too much may be a precursor to certain diseases.

According to some scientific research, everyone has to have several dreams every day, that is, many images are formed in the brain, which is why sometimes I feel that my dreams are messy, and the places and people are very mixed or unconnected, and we can only remember some of them, or a part of each dream. It's normal to dream, but if it's always stressful dreams, then you're stressed out and need relief. Dream interpretation stuff is not very scientific.

In addition to the positive effect of dreams on the human brain in the same way that computers process data, it brings the connections between the cerebral cortex into a much better stage. Dreams also play a very positive role in maintaining the mental health of a human being. Many patients with chronic depression are plagued by chaotic dreams or abnormal sleep with lack of dreams for a long time.

When they had a computer-adjusted brainwave sleep**, their condition improved to varying degrees. Dreaming has many benefits for people, and dreaming can exercise the function of the brain. Dreaming is a kind of working program of the human brain, which organizes the information that the brain receives during the day, and the information that the brain cannot process during the day can be well processed in the dream, and the problems that cannot be solved during the day can be solved in the dream at night.

Dreaming itself has certain benefits for people and sleep, unless you can't sleep peacefully at night, and you have obvious sleepiness during the day, which affects your normal work and life, you should find a doctor to find the cause and carry out **.

When dreaming at night, the human brain is generally conscious, but the reflex arc time is a little slower than usual.

Between sleeps, brain waves become slow and smooth, which is consistent with what people had guessed at first. So in fact, the brain is conscious when dreaming.

The brain is always working, in fact, people are also dreaming at night.

The reason why some dreams are remembered is because I woke up from a light sleep when I dreamed.

When dreaming at night, the brain is equivalent to a process of sorting, classifying the knowledge absorbed during the day into storage, so there will be similar dreams, so it is said that there are thoughts and dreams at night.

As for the real dreaming mechanism, there are many theories now, but none of them are certain.

I think there is.

I have a habit of waking up early the next day, I don't set an alarm, but I remind myself before going to bed that I have to wake up early tomorrow, and I can always get up as early as I want, sometimes exactly what time I wake up the next day. So there should be a subconscious.

Once, as usual, I told myself I was going to wake up by seven o'clock the next day and went to sleep. Halfway through my sleep, I asked myself in my sleep, "Aren't you going to wake up early, what time is it?" Then I woke up immediately and looked at my phone, it was 6:40.

It's also very weird.
