Every night our conscience shuts itself down when we go to sleep and it reconnects when we wake up, ready for a new day. While we rest our brains remain active all night long and part of this brain activity produces almost real and sometimes frightening images during the REM (Rapid Eye Movement) phase of sleep, which we call dreams or nightmares. On average we spend 19.3 years of our lives in this trance phase we call sleep, and although that time represents almost a third of our lives, we still know very little about what goes on in our brain during sleep. Today we publish 10 facts about dreams, which hopefully will help you to clarify some common doubts on this subject.
10. We Forget 90% of Our Dreams
5 minutes after waking we no longer remember half of our dreams and 10 minutes later, 90% have already gone! It seems like a waste of dreams, since we can have between 3 and 7 dreams in one night, and on top of that, on average, we spent about 6 years of our lives dreaming.
9. Some People’s Dreams Are Black and White
12% of people dream only in black and white, and the rest in color. It is not known why these people dream in black and white but the truth is that it is so. There are also themes that are common in dreams, with situations related to school, being persecuted, sexual experiences, falls, car accidents, a person known to be dead in the dream and others. It is not known whether the most violent dreams are more emotionally charged to a person who dreams in color or who dreams in black and white.
8. When We Dream the Body is Paralyzed
In the first 90 minutes of sleep, we go through some stages of light sleep and deep sleep. After that we enter the REM phase (Rapid Eye Movement). At this stage our body becomes paralyzed, as the release of certain neurotransmitters is blocked and the larger muscles stop working. There are however, people with this REM stage in which the neurotransmitters are not blocked and end up expressing with the body the dream they are having. The REM phase is one in which the brain is most active.
7. Women Have More Nightmares Than Men
A study by psychologist Jennie Parker of the University of West of England found that women have more nightmares than men. Women not only reported more nightmares, but also that their nightmares were more intense than those of men.
6. Blind People Also Dream About
People who became blind after being born see images in their dreams. People who were born blind do not see images but their dreams are equally lived and involve other senses like sound, smell, touch and emotions.
