What does the REM phase mean?

REM sleep is a stage in the normal sleep process of humans or animals, this stage is the deepest of the entire sleep process and most dreams occur at this time.
REM sleep, also known as rapid eye movement sleep, is a stage in the whole process of normal sleep in humans and animals. The eyeballs move rapidly during this stage, and the brain waves, or neurons in the brain at this time are the same as when a person is awake, characterized by rapid, low-voltage desynchronization.
During this period, the muscles of the person’s body appear to be relaxed, and it is during this phase that most of the deeply affecting dreams occur. The entire REM period lasts about one and a half to two hours or so, and is important for memory storage, organization and integration.
REM sleep is an important stage in the sleep process and has a significant impact on the human body, not only affecting the quality of sleep, but also particularly important for the storage and development of human memory.
It is recommended that patients with sleep problems seek timely medical attention to assess their condition and follow medical advice.
