What are the bad things about not dreaming?

Everyone generally goes through 4 to 6 sleep cycles during sleep and dreams in each cycle. This means that under normal circumstances, people will dream 4 to 6 dreams every night, but it is easier to dream when they are too tired, sick, facing difficulties or major changes, anxiety, tension, etc.

Dreams come to our sleep every night. The only difference is that sometimes we realize them and sometimes we don't. This mainly depends on whether we wake up during a certain sleep cycle and whether the sleep cycle is interrupted. Research has found that if people wake up at the end of a certain sleep cycle, the content of dreams often cannot be recalled, because the nature of dreams is short-term memories and will soon be forgotten if they are not repeated many times or transformed into long-term memories. But if the sleep cycle is interrupted and the person is dreaming, the content of the dream can be remembered. Therefore, most of the dreams people remember after waking up belong to the last dream they had.

Some experts pointed out that the so-called 'dreamless night' is just that we don't remember having dreamed at night. But if you often feel that 'the night is long and the dream is too long', it is a sign that the quality of sleep is not high. If a person realizes that he keeps dreaming at night, it means that his sleep has been interrupted many times; if he remembers having several dreams, it means that he has woken up several times during the night. Sleep is intermittent and intermittent, which naturally makes people feel tired and weak.

Normal dream activity is one of the important factors to ensure the vitality of the body. As some research experts have said: The impact of dreams on sleep is actually a physiological confrontation between nature and the outside world. Only by controlling some physiological instinctive movements or reactions can dreams and sleep actively cooperate, which is beneficial to human health.
