Sleep can be divided into two types/phases, REM sleep and non-REM (NREM). In normal sleep, the two phases are always repeated in the sleep, with a length of approximately 90 minutes each. NREM has four phases, and the fourth phase is the deep sleep phase. REM is the deepest phase and often called the dream phase.
But when the cycle is interrupted, or when a person does not experience REM and NREM cycles normally, the body will experience a variety of adverse effects such as feeling tired, decreased the ability to concentrate, impaired metabolism, and so forth.
