Around one-third of our lives, we sleep—and we dream about that time. While there are several hypotheses to understand why we dream, no one knows their expectations or the significance of the dreams fully. Some researchers believe it has symbolic significance, whereas others believe it has to do with dreams.
What scientists know is that every time they sleep, almost everyone dreams, and these dreams can be interesting, thrilling, horrific, or simply strange. Here are 10 things about dreams that you need to know.
The brain is active throughout the night, with especially strong brain activity during REM sleep, when we dream.
Adults and babies both dream about two hours a night, even though when they wake they don’t remember them. In reality, researchers have discovered that dreams typically last between five and 20 minutes per night and each dream.
For an average of six years, people have dreamed of a normal life.
Most Dreams Are Forgotten
Only after waking up, 95% of all dreams are rapidly forgotten. One theory is that the brain changes occurring during sleep do not help the processing and storing of information required to shape memory, since it is a difficult dream to recall.
Brain scans of sleeping persons showed that the front lobes – a region that plays an important role in the development of memory – are inactive during fast movement of the eye (REM), a dreaming period.
Research in 2016 in the journal Behavioral and Brain Sciences has found that it can also alter those neurotransmitters’ levels by forgetting dreams.
Another research, published in Frontiers of Psychology, found that the density of the medial prefrontal cortex was related to dreaming recalls (MPFC). Increased dream recall was recorded by participants with a higher density of white matter.
Not All Dreams Are in Color
Although most people report colorful dreams, about 12 percent state that they dream only in black and white. Soft pastel colors are the most commonly selected in studies where the dreamers have been awoken and asked to choose colors from the charts that fit their dreams.
People under the age of 25 seldom report black and white dreaming. But people over the age of 55 record about 25 percent of the time black and white dreaming.
This is the product of exposure to black and white TV for children, researchers claim. This theory has been reinforced by an earlier study that showed that there were seldom color dreams recorded in the 1940s.
Men and Women Dream Differently
In terms of the quality of their dreams, researchers identified several gaps between men and women. Men indicated that they dream more about guns than women in many studies, while women dreamed about clothing references more often than men.
Another study found that males’ dreams appear to be more violent, with more rejection, more exclusive, and more conversational than physical activity. Women’s dreams involve more interaction.
Women appear to have some more characteristic, slightly longer dreams. In dreams, men dream twice as much about other men as they do with women, while women seem to dream about both sexes alike. They also dream.
