In the process, the body’s reaction to external stimuli is noticeably reduced and, as it is believed, the central nervous system is switched to another important process – analysis and adjustment of the operation of the internal organs.

Scientists found out that the brain is not relaxing at night, but organizes a complex and ordered sleep system – cycles. The cycle consists of phases: Dunda, several stages of slow sleep, fast sleep, when usually and turns on "Cinema". By the way, during experiments, scientists have discovered an amazing fact: animals also see a wide variety of dreams, that’s just erotic ever.

Other headquarters of the brain are responsible for each phase of sleep. If a person has four to six full cycles in a healthy dream, then animals are very different in animals. In modern conditions, difficulties are preserved with the description of the "sleepy" scenario only at the lower vertebrates and insects – experts have not yet come up with how to examine them.

It is possible that sharks are also sleeping, which are descended to relax on the bottom of the sea. Their eyes remain open, and they are vigorously watching the surrounding.
