In recent years, the theory has gained popularity that a person can remember information and even study in a dream. We decided to check if this hypothesis has scientific justifications.

Publications with proposals to help start training in a dream appeared on many resources. In a dream they offer to master Foreign languages, learn to play on musical instruments And even pull up Mathematics. The question of the possibility of learning in a dream has repeatedly asked users "Yandex.Zen", The answer also tried to give the editorial office"TASS".

According to scientists, people Conduct In a dream about a third of your life. Now, in the age of productivity and gaining popularity of time management, theories have appeared on how to spend this time with maximum benefit, learning something new in the process. To learn a poem, remember a dozen new words in a foreign language, prepare for the exam while you sleep - all this sounds very tempting for any person living in the fast rhythm of a big city. Learning process in a dream called "hypnopaedia".

It is known that a dream shares At two stages: slow sleep (orthodox) and fast (paradoxical). The first stage occurs after falling asleep and lasts from 60 to 90 minutes. During it, the metabolism of metabolism, relaxation of muscles and a decrease in body temperature occur. Slow sleep replaces fast, it is paradoxical. Its duration is much smaller - from only 10 to 20 minutes. This stage is characterized by an increase in the heartbeat, an increase in temperature, as well as a reduction in the facial muscles and limb muscles.

Exploring these stages, scientists conducted experiment. Sleeping volunteers were removed by an electroencephalogram to show what is happening with the activity of the brain during sleep, conducted electroculography to track the movement of the eyes and electrical activity of the eye muscles, and an electromyography that allows to track the state of skeletal muscles. As a result, scientists have found that the processing of external information is blocked during slow sleep due to its depth. However, in the fast phase, everything was the other way around: the motor cortex, it is also the motor crust of the brain, gave the necessary signals so that a person could make a finger, reacting to a certain word. True, such a reaction was possible only if a person already knew this word. The study made it possible to confirm the assumption that the human brain in the quick stages of sleep can not only perceive information, but also analyze it. The same experiment completely refuted the statement that sleeping are isolated from the environment.

With the analysis of information is more or less clear. But can she linger for a long time in human memory? In 2017 in the journal Nature An article was published, the authors of which reported that people could really recall the information that they heard in a dream. The only condition for its memorization is to be in that very fast stage of sleep during its perception. Scientists have demonstrated that at this moment waves appear in the human brain that indicate the learning process, that is, during a quick, or paradoxical, phase, a person is able to continuously absorb information.

As for the study of foreign languages in a dream - this is definitely impossible today. Scientists have not yet found a way that will make new words to remember, being in a state of sleep. During the study of a foreign language, neurons throughout the brain are used, so the maximum that the human brain is capable of during a quick phase of sleep is the processing of already learned words. Therefore, for productive learning Consult memorize 10-20 new words half an hour before bedtime.

Thus, based on scientific research and experiments, the following conclusion can be drawn. In the fast phase of sleep, a person can really analyze, remember and keep in memory what he hears in a dream (if there are no words previously unknown to him among this stream), as well as process the information already received and remember it deeperly. At the same time, the capabilities of our brain do not allow us to study something fundamentally new in any phase of sleep, or we still do not know how to activate them for this purpose.
