Dreams have long worried and interested humanity. What theories explaining the nature and mechanism of dreams have not been proposed by poets, scientists and philosophers! Modern science has revealed several secrets of dreams, but it has not been fully clarified how, why and why we see dreams.

Step 1
A third of life, as is known from the school curriculum, a person sleeps. For a long time, it was completely unknown what happens to the brain during sleep. Only in the middle of the last century, an American scientist, using an electroencephalogram taken from his sleeping son, proved that the brain is not inert during sleep, but is active.
Step 2
Scientists have proven that the structure of sleep is cyclical. If a person is healthy, then his sleep begins with a phase of slow wave sleep, which lasts about 5-10 minutes. Then the second stage begins - about another 20 minutes. The third and fourth phases lasts another half hour or three quarters of an hour, then the sleeping brain again enters the second phase of slow wave sleep. This is followed by a five-minute REM dreaming phase. During full sleep, this cycle can be repeated five times. With each new cycle, the REM sleep phase increases.
Step 3
During REM sleep, a sleeping person can observe rapid movement of the eyeballs. It is believed that this phase is associated with dreams. Ninety percent of those awakened during this period can retell their dreams in full. Despite the movement of the eyes during this stage and the fact that the encephalogram of this stage is more similar to the state during wakefulness, during this time the entire human body is most relaxed.
Step 4
There is an opinion that it is the violation of the REM sleep phase that is fraught with problems for the human psyche. And those who were awakened during the REM sleep period felt less rested than those who were awakened during the REM sleep phase.
Step 5
There is a theory that the phase of slow wave sleep is associated with replenishment of the body's energy expenditures during wakefulness, and the phase of REM sleep has a beneficial effect on people's ability to think creatively.
Step 6
People who are blind from birth do not dream, but they have insects, for example, fruit flies. A person sees dreams every night, but he forgets most of them.
