People have found their own meanings of dreams since ancient times. In more recent years, Sigmund Freud believed that a dream provided a window to our unconscious thoughts, while Alfred Adler said that a dream can help us solve real-life problems.
The purpose of dreams is still not known completely yet recent advances in both the physiology and psychology of dreams offer some interesting insights.
Dreaming does occur in both stages of REM sleep and non-REM sleep. In non-REM sleep, people are likely to produce a thinking or meditative dream. Scientists do know less about non-REM sleep than counterpart, REM sleep.
Most people’s dreams during REM sleep have a storyline, which is where all the sounds, visuals even tactile kinds of experiences set in. Many researchers also believe that REM sleep is crucial to problem-solving and sorting out meaningful as opposed to inconsequential events during the day. REM is said to be important to the organization of memory, which is probably why students should get a good night’s rest before a big exam.
While scientists still do not know the precise function of dreams, much contemporary research focuses on their connection to memory and figuring out problems. If you have sleeping problems or your dreams are tending to interrupt your sleep, consult with a doctor.
