As soon as they do not call a dream: the second reality, the fourth dimension, the journey of the soul … And yet, scientists still cannot give an exact answer to the question: why does a person dream.
In ancient times, many superstitions were associated with sleep: for example, sleeping children closed their mouths so that the soul would not fly away and get lost. However, in our enlightened era, dreams are still treated with considerable reverence: allegedly a prophecy appears to a person in a dream, you just need to be able to decipher it.
Dream: another reality?
Once upon a time, the Brahmins of Ancient India suggested that sleep is the journey of the soul. The Europeans believed that in a dream the soul leaves the body, all its flights are dreams. Modern science has a slightly different point of view on this matter, but in some ways it echoes ancient interpretations: sleep is just a different mode of brain activity. That is, the brain does not stop working even for a minute.
It is still unclear how dreams happen and why a person falls asleep? The famous Z. Freud was one of the first scientists who tried to explain dreams. So, he considered sleep to be a kind of connection with the subconscious, where the most secret desires, aspirations and fears are hidden. Everything once seen, felt, heard is deposited in the subconscious. With the help of a competent psychotherapist, you can open even the deepest layers of the subconscious and thereby find answers to many questions.
Thus, dreams are not a random mosaic of pictures, but a kind of symbols of an associative series that the brain shuffles in the most bizarre way. Some scientists believe that this is how the brain clears the space of the matrix from unnecessary and irrelevant rubbish. Others believe that the brain in a dream is trying to solve some problems and suggests a variety of options.
A lot is still being said about prophetic dreams, but scientists explain this fact from the standpoint of science. When interpreting a dream, a person often sets himself up for a certain scenario, including the mechanism of self-hypnosis. And if you expect a bad development of events, then you can see it in any more or less negative situation. Often in a dream a person is sick or sees some pictures that refer to diseases. This is not a prophetic dream, it is the body that sends signals to the subconscious that there are problems. Therefore, restless dreams and nightmares can be observed in people who are unaware of their illness. In addition, emotions that are hidden inside and need to be released can also manifest themselves in disturbing dreams. If nightmares are constantly tormenting, then it is necessary to find out their cause — a psychologist can help with this. It is also worth paying attention if you constantly dream. Usually, dreams come only in the REM phase, and full recovery requires the phase of non-REM sleep.
Sleep as the basis of a healthy lifestyle
A healthy lifestyle (HLS) begins with a routine. First of all, with the sleep mode. One of the most common myths about sleep: you can “catch up” with compensatory rest on weekends, for example. This is fundamentally wrong. If during the week the body feels a serious lack of sleep, then it cannot be filled with any days off. Moreover, this approach is extremely unhelpful: the process of recovery of the body is cyclical, that is, uniform. Therefore, the intervals between sleep and wakefulness should be approximately the same.
Another important aspect of a healthy lifestyle related to sleep is physical activity in the late evening hours. There is a misconception that exercising before bed makes you fall asleep faster. But any activity leads to accelerated blood circulation and, as a result, excitation of the muscles, while they need to be in a relaxed state. Therefore, it is more productive to exercise at least four hours before bedtime.
Sleep lovers should know that too much sleep is just as bad as not enough. Normal normal sleep requires seven to nine hours. It is important to maintain a balance here (one of the pillars of a healthy lifestyle): if you sleep a little, but at the same time you feel quite cheerful, there is no drowsiness, your working capacity is at the level — there is nothing to worry about. But if you want to sleep all the time, and you sleep a lot and for a long time, then this is a reason to see a doctor. Such sleep disturbances, coupled with sleep apnea syndrome (snoring), can lead to a stroke, doctors say.
Good quality sleep is the key to calm nerves, which is very important in our time. In a dream, the brain does not rest, but the nervous system relaxes, gaining strength for the next day.
How hormones affect sleep
Hormones have a great impact on the human body: almost no process in it can do without these substances produced by the endocrine glands. They did not bypass their attention and the regulation of sleep.
There are many reasons why sleep is disturbed, but one of the most common is the lack of the so-called sleep hormone. This is melatonin, produced strictly in accordance with daily biorhythms. So, most of all it is produced by the body in the dead of night until five in the morning — at this time a person has the sweetest dream. The explanation for this is simple: melatonin is actively produced in the dark.
By the way, a lack of melatonin causes restless, weak sleep in the elderly. As we age, melatonin synthesis decreases (as well as other processes), which is why many older patients complain of unproductive sleep.
Melatonin is responsible for more than just sleep. With its help, some important hormones are formed (for example, leptin is a satiety hormone), the protective properties of the immune system are enhanced (it has been noticed that people with chronic sleep deprivation get sick more often than those who sleep well and according to the regime), the emotional state improves.
If necessary, the doctor can prescribe drugs containing melatonin: they will provide the necessary amount of the hormone in the body, which means that there will be good sleep, good rest and a restored nervous system.
But not only one preparations is worth maintaining good health. It is important to go to bed and get up at about the same time interval: thus, daily biorhythms will work smoothly and develop the necessary melatonin standards.
