The Sleep Pendulum

Who among us has not dreamed of sleeping longer and finally getting a good rest? Humans are the only beings on Earth who can afford to sleep for eight hours straight… but that’s not very beneficial. At the same time, most of our insomnia is imaginary, and melatonin, which is used to combat it, does not help. We already know some things about sleep. For example, we have phases of slow and rapid sleep - thanks to their alternation, a person is able to think and exist in general. But the main mysteries: what is the brain engaged in during sleep? Why do we dream? How does rapid sleep occur? - still remain unanswered. The scientific search is all the more interesting.
