Why does a person need a dream?

The exact answer to this question has not yet been found. However, scientists presented facts confirming that sleep is extremely important for humans. At this time, the work of all organs and systems of the body slows down. Even the heart rate slows down, which makes it possible to relax the heart muscle. During sleep, cell regeneration is most active. It is established that during this period there is an ordering of emotions and memories received during wakefulness.

The brain does not sleep!

In the human brain is a center that controls the biological clock. When the time of sleep approaches, this center is triggered, and the consciousness begins to gradually turn off. First of all, there is a slowdown in the work of neurons that are responsible for associative connections. The phase of deep sleep comes. Together with the disconnection of consciousness, the transmission paths are disconnected from the senses (vision, hearing, smell). All thought processes are regulated by a special mode of interaction and functioning of certain groups of neurons. Thus, when the period of sleep begins, the human brain begins to work in a different mode. Moreover, the intensity of these processes is different at different stages of sleep. So sleep is a fairly active and important process.
