The reasons people dream when they go to sleep

Dreams are experiences, illusions in the mind when sleeping. The dream phenomenon happens in almost everyone but not everyone knows the cause and how to control their dreams.

Let's understand more about why we have beautiful dreams, but sometimes we have terrible nightmares .

1. Filled with wishes

In the early twentieth century, psychologist Sigmund Freud studied the dream behavior of hundreds of people, thereby giving the theory of realizing the unfulfilled desire of each person in a dream . This theory has caused a great buzz and is considered one of the first achievements of dream research.

Accordingly, the dream is nothing to be afraid of, it is simply to accomplish what you want when you are awake : to go to places where you have never come or hold hands with your "dream man" . me

In a dream, the human mind is no longer limited by any barrier and can overcome the limits that we cannot step through the day.

This theory also explains the cause of nightmares . It is to help solve or delete from the top of the image you do not want. Sigmund Freud says, if you dream of a lost family member, even though it is not what you want, it is also a way to 'fulfill your wish' .

Or as if you are having a conflict with your loved one, removing that person's image in the dream will make everything easier for you. In this way, Freud helped many of his patients detect and arouse 'hidden' emotions that they could not solve.

2. Forget and remember

When learning about the causes of dreams, scientists have come up with two quite contradictory theories. But surprisingly, when combined, they help create a new theory that is quite complete and comprehensive: it is "forget" and "remember".

The "forget" theory holds that our dreaming every night is to help the brain get rid of unwanted connections that have formed during our waking hours.

Simply put, the dream is like a broom, it will help 'clean up' useless things and make the brain have more space to continue storing information. The basis of this theory is that we often cannot remember what we dreamed of.

In contrast, the "remember" theory suggests, the dream will help strengthen memory and what we have experienced . This is based on a few studies that show that if we have learned what we have learned in our dreams, we will remember longer than usual.

The example is quite clear in this case that when a person experiences an extremely painful incident, when they sleep, they often have terrible dreams related to that experience. This will become more and more deep into the mind, making them unable to forget. The only way to deal with it is to take tranquilizers, or find ways to interact with the sick, keep them from sleeping as long as possible; even when they are exhausted to prevent "remembering" from happening.

3. The mechanism of 'fake death'

According to scientists, the dream is the evolution of the 'fake death' mechanism in animals. When in danger, the animals often have many ways to defend themselves such as ruffled feathers, run away, fight back . and fake death makes the enemy not pay attention anymore. During this period, the brain is fully awake and functioning normally along with the secretion of dopamine - which has a neurotransmitter effect.

While dreaming, we humans also secrete such substances. Under the action of dopamine, the dream fills our minds with countless stimuli and emotions.

Later, Finnish psychologist Antti Revonsuo "upgraded" , supplementing the theory. Accordingly, the human dream is even the evolution of the "fake death" mechanism. He said that the dream is a simulation of threats, helping people learn to "handle" that danger safely without suffering any physical damage. As a result, people will react better and faster if they accidentally dream about threats at night.

4. Restructuring traumatic past

Sleep disturbance researcher Ernest Hartmann talks about the contemporary theory of dreams that says: any experience in a dream is associated with emotions.

If something is too painful and we don't want to remember it, the brain will "refactor" by imposing a new experience instead of the old experience we experience.

For example, if a person is stuck at work, in a dream, he will dream that he is walking in a maze without a way out. Although they bring a feeling of impasse, this will help that person relieve pressure on his problem.

The more problems and emotions, the more and more complicated the dream. Thus, the dream is merely a connection made to link and restructure your emotions. Maybe this is an evolution of our ancestors to deal with mental trauma that they cannot solve.

Although the dream is sometimes very strange, it also has an important role, affecting our thinking. However, there is one thing that no one has fully explained, the dream is an evolution, or just a coincidence.
