REM-NREM

Many of us think that we don't experince dreams, or do not have them at all, when in reality we dream everyday as we sleep. There are intervals in the dreaming process, which can be defined as REM, or rapid eye movement. There are two types of sleep, the first one, which we already have mentioned, **REM**. The second is simply the opposite, **NREM** **(non rapid eye mvement)**. REM sleep in adult humans typically occupies **20–25%** of total sleep, about **90–120** minutes of a night's sleep. During a normal night of sleep, humans usually experience about four or five periods of **REM** sleep; they are quite short at the beginning of the night and longer toward the end. Many tend to wake, or experience a period of very light sleep, for a short time immediately after a session of REM. The amont of REM sleep equilizes to the age of a person. A newborn baby sleeps **80 %** of the time, expiriencing REM sleep. In REM, usually the dreams are being recalled and somewhat recognized. As a person gets older, the amount of sleep in an average day decreases, so REM doesn't come to them as often.

There are many memory-related theories. According to such, **REM** sleep takes great participation in memorization and consolidtion of the required material. It helps you get rid of some of the weak fears that you experience as awake; if you keep on going back to the same dream, you can learn to control them. You can motivate your own actions as you progress in the dream. The studies have shown that people who get **7-9** hours of sleep are most likely to experience **REM** sleep at least 3 times a week. REM sleep helps you disocover yourself as in your unconcious during the sleeping process, helping you conciously as you function during the day.
