For many, the process of sleep is a mystery. It is difficult to imagine what brains do during sleep, why human dream, or even why human face some nightmares during their sleep.

It also has been considered that dreams that can be reported by the dreamers are happening during REMs sleep. According to Shafton, sleepers who were awakened from REM sleep are usually able to report their dreams in about eighty to ninety-five percent of their dreams. The emotions, however, that the sleepers have after been awakened from REM sleep are often negative emotions. Conversely, when they are awakened from NREM sleep, they are more likely to report positive emotions. McNamara (2008) explains that there are more negative feelings during REM dreams because though REM sleep the amygdala, an almond-shaped inside human's brain that associated with emotions, is highly operated. It, therefore, specializes in processing annoying and negative feelings, such as aggression, irritation, or even intense panic. Most importantly, normal individuals fall asleep during NREM sleep, but people who are facing intense depression go directly to REM sleep. He illustrates that REM sleep is connected with all abominable emotions, and when a person have too much REM sleep, they are more likely to have many unpleasant emotions. On the other hand, there are “White Dreams” which is when a person says that they were dreaming, but they cannot recall or report the purpose of their dreams. Hori, Ogawa, Abe, Nittono (2008) claim that through REM sleep, the percentage of dreams with more vivid and clearer recall is higher than through NREM sleep.
