Dreams are delusory experiences that occur during specific periods of sleep. They are most active during the rapid eye movement stage of sleep when you are less likely to recall the dream. Sleep’s importance in regulating our metabolism, blood pressure, brain function, and other elements of health is well understood. However, scholars have struggled to explain the role of dreams.
While awake, your ideas follow a certain logic. While sleeping, your brain continues to function, but your thoughts and dreams frequently make little or no sense. This could be because the emotional centres of the brain, rather than the rational sections, initiate dreams.
Though there is no conclusive evidence, dreams are frequently autobiographical reflections on previous activities, discussions, or other life events.
1. Almost Majority of Dreams Are Forgotten
Up to 95% of all dreams are soon forgotten upon awakening. According to one explanation concerning why dreams are so difficult to recall, the changes in the brain that occur during sleep do not allow for the processing and storage of information necessary for memory formation to occur.
Brain scans of sleeping subjects have revealed that the frontal lobes—the region responsible for memory formation—are dormant during REM sleep, the stage during which dreams occur.
According to a 2016 study published in the journal Behavioral and Brain Sciences, dream forgetfulness may also be caused by changes in the levels of certain neurotransmitters during REM sleep, specifically acetylcholine and norepinephrine.
Another study, published in Frontiers of Psychology, discovered a connection between dream recollection and the medial prefrontal cortex’s brain matter density (MPFC). Participants with a higher white matter density reported having a greater ability to recollect dreams.
2. Not Every Dream Is Colorful
While the majority of people report dreaming in colour, approximately 12% report dreaming only in black and white. In tests in which dreamers were awoken and asked to choose colours from a chart that matched those in their dreams, the most often picked hues were soft pastels.
Individuals under the age of 25 rarely report having black-and-white dreams. However, those over the age of 55 report having black and white dreams roughly 25% of the time. According to researchers, this difference is the result of early exposure to black and white television in childhood. This notion is backed up by an older study, which discovered that adults in the 1940s rarely reported having colour dreams.
3. Visual Dreaming Is Possible for the Blind
In one study, researchers discovered that persons who have been blind since birth continued to have visual imagery in their dreams and also retained eye movements associated with visual dream recall.
Although blind subjects reported fewer eye movements during REM than sighted participants, they reported the same dream feelings, including visual content.
4. Men and Women Dream in Distinct Ways
Researchers discovered certain disparities in the content of men’s and women’s dreams. Males reported thinking about weapons substantially more frequently than women, while women reported dreaming about apparel more frequently than men.
Another study discovered that men’s dreams are more aggressive and physical in nature, but women’s dreams are more rejection and exclusion focused, with more talk than physical activity.
Women experience slightly longer dreams with a greater number of characters. When it comes to dreaming characters, men dream twice as frequently about other men as they do about women, while women dream equally about both genders.
5.Animals Probably Dream
Many believe that when a sleeping dog or cat wags its tail or swats its paws, it is dreaming. While it is difficult to know for certain whether this is true, studies believe that the majority of animals, including mammals, birds, reptiles, and fish, do experience sleep stages, including REM and non-REM sleep, which suggests they do dream.
6. You Can Control Your Dreams
A lucid dream occurs when you are aware that you are dreaming while still sleeping. Lucid dreaming is believed to be a condition of consciousness and rapid eye movement sleep in which you can frequently guide or control the dream content.
7. You Are Immobilized While You Are Dreaming
The voluntary muscles are paralyzed during REM sleep. The condition is referred to as REM atonia, and it prevents you from acting out your dreams while sleeping. Simply put, your body does not move because motor neurons are not triggered.
While it may be alarming, experts say that the sensation is totally normal and should last only a few minutes until the normal muscular function returns.
