Sleep and Dream

Sleep and dream sleep are behavioral states characterized by little physical activity and little external consciousness. Sleep actually consists of two distinct different states called REM sleep (rapid eye movement) and non-REM sleep (non rapid eye movement). Using NREM sleep, it is further divided into 1 to 4 stages according to the size and speed of the brain waves. The first step is the stage of rest or sleep. For example, you are bored, doing nothing but listening to what the teacher says, so people snooze in the class.

REM sleep is the main sleep stage of a dream. Understanding of human dreams is based on a subjective report which was recorded mainly when waking up from sleep. Dreams can occur during NREM sleep, but the dreams of those waking up with REM sleep are more frequent, their dreams are luxurious, vivid and fantastic. It is still difficult to achieve the function of a dream, but the pattern of brain activity during REM sleep provides some clues about the characteristic attributes of a dream. For example, activation of the edge structure during REM sleep may be related to high emotional content of dreams, but deactivation of the front area may lead to a dream of "strange" (Time and space distortion, lack of insight and control, etc.)

REM sleep is the main time to dream. Dreams can happen at any time during the sleep cycle, but dreams are clearer and easier to remember when they appear at the Rem stage (Feldman, R., p. 144). Since the discovery of REM sleep in 1953, REM sleep has become the main focus of dream research. Research has been conducted to support the theory that REM sleep can be the most important part of the sleep cycle. In the experiment, those who were allowed to go to sleep but who were not allowed to enter REM stage got worse in the next day's assignment. People who were allowed to complete all sleep cycles including REM worked better in the mission of the next day (Dixon, M. & Hayes, L. 1999). The importance of REM sleep depends on the psychological method explaining it
