What is the role of sleep for humans? How do dreams arise?

Sleep plays a very important role in a person’s life. According to statistics, a person spends a whole third of his life in a dream. And this is not surprising, because it is in a dream that the best conditions are created for restoring the working capacity of the nervous system, the functional state of other organs and systems of the body is restored. It is not for nothing that almost all recommendations for health improvement necessarily indicate the need for good sleep: this is a means of preventing the development of many diseases. The signals from the senses that enter the brain during sleep are combined with the work of the brain. This is how dreams arise.
