All people dream, but to some dreams we give more and some less significance. For some people, dreams are only vague and disjointed images of the mind, for others, dreams are guides who show us what is important for us in life. Our brain is active even when it travels in the “land of dreams”. The body is resting, but neurological functions are not interrupted. There are two types of sleep – NREM and REM sleep. Adults sleep in NREM 75-80% of the total sleep. That sleep is characterized by a decline in metabolic activity, blood pressure and the number of heart rate and can be divided into two phases: light and deep sleep. In light sleep, the body changes its position 40 times during the night for circulation to run smoothly and muscles stay mobile. In deep sleep both muscles and brain are extremely relaxed. But most dreams occur in the REM phase of sleep. It is experimentally proven that people can accurately describe dreams if they wake up during this sleep, and after you spend just 5 minutes of REM sleep, the memory of the dream goes foggy, and if 10 minutes pass, you will not remember the dream at all. Those who say they do not dream are those who wake up immediately after REM phase which lasts on average 15-20 minutes and immediately entering a new NREM stage which lasts from 60-90 minutes.
Some psychologists argue that dreams are a way in which the brain organizes overall memory and memory created during the day. Others say they are “by-product” in cleaning toxins or unnecessary content of the brain. The average person spends up to 6 years of his life dreaming. There is a difference in the dreams of men and women, men often dream of people of the same sex, while women dream equally members of both sexes. Male dreams are full of aggression, while females take longer and involve more characters. Both sexes equally often dream that their partner is cheating, which is one of the most common dreams. Such a dream does not mean actual cheating but is a manifestation of subconscious fear of loneliness and loss.
Dreams are like representation of unconscious desires and urge to which we cannot influence. The father of psychoanalysis, Sigmund Freud, has been studying all this. But they were also studied for techniques of controlling dreams. The dream we are aware of is experienced during the afternoon nap.
