It is said that five minutes after the end of a dream, we have forgotten 50 percent of the dream's content. Ten minutes later, we've forgotten 90 percent of its content.
People have several dreams each night, but probably forget about 95 percent of them. Here are 10 more fascinating facts about dreaming…
Within five minutes of a dream ending, we forget 50 percent of its content, and 90 percent of our dream's detail is lost only 10 minutes later. But why? Dreams can be intense emotional experiences with a vividness approaching waking life!
“Since dreams are thought to primarily occur during REM sleep, the sleep stage when the MCH cells turn on, activation of these cells may prevent the content of a dream from being stored in the hippocampus – consequently, the dream is quickly forgotten.”
WE FORGET almost all dreams soon after waking up. Our forgetfulness is generally attributed to neurochemical conditions in the brain that occur during REM sleep, a phase of sleep characterized by rapid eye movements and dreaming.
Our brain is not fully developed when we are born—it continues to grow and change during this important period of our lives. And, as our brain develops, so does our memory.
A person may not remember the events of their dreams because they cannot access that information once they are awake. In a 2016 article in the journal Behavioral and Brain Sciences, researchers posit that people forget their dreams due to changing levels of acetylcholine and norepinephrine during sleep.
The dream you're most likely to remember is the one you had just before waking up. Dreams tend to occur during the rapid eye movement (REM) cycle of sleep. A 2019 study noted that our ability to make memories is impaired during REM sleep. That would help explain why we're prone to forgetting dreams.
The whole literature agrees that dream recall progressively decreases from the beginning of adulthood - not in old age - and that dream reports become less intense, perceptually and emotionally. This evolution occurs faster in men than women, with gender differences in the content of dreams.
Shared dreams definition
Shared dreaming is the idea that two or more people can share the same dream environment. The degree to which the dream is shared can vary, from simply having common elements or events that happen in each person's dream, to the entire dream being identical.
It is said that five minutes after the end of a dream, we have forgotten 50 percent of the dream's content. Ten minutes later, we've forgotten 90 percent of its content.
According to Forbes business, only eight percent of the world's population manage to turn their dreams into reality. These statistics are repeatedly quoted on many sites such as inc.com, lifehack.org and many others.
We Dream Every Night
During a typical lifetime, people spend an average of six years dreaming.
One early study of 17- to 70-year-old college-educated participants (n = 295) found that dream recall frequency (DRF) was at its highest level (9.8 dreams/month) in the late teens, progressively lower at ages 30–39 (6.1/month), 40–49 (4.2/month), and 50–59 (3.7/month) and then somewhat higher again at ages 60–69 (4.5/ ...
In questionnaire surveys, up to 6.5% of people report that they 'never dream'. Although most of these people report having dreamed at some point in the past, roughly 1 in every 250 people say that they can't remember ever dreaming — not even once.
Kahn, Dement, Fisher, and Barmack (1962) wrote that “with careful interrogation close to the time of dreaming, color was found to be present in 82.7% of the dreams” and Herman, Roffwarg, and Tauber (1968) discovered that coloured dreaming was reported after 69% of REM awakenings of their subjects.
The science of dreams shows that recurring dreams may reflect unresolved conflicts in the dreamer's life. Recurring dreams often occur during times of stress, or over long periods of time, sometimes several years or even a lifetime.
Wu says it is indeed possible to train your brain to be ready to recall dreams by working on your intentions during the day. "Simply by having the intention to remember your dreams at bedtime, someone can increase their dream recall," she explains.
During non-REM sleep, the thalamus is inactive, but during REM sleep, when we are dreaming, the thalamus is active, sending the cerebral cortex images, sounds, and sensations, which is why we are able to hear, feel, and see in our dreams similarly to how we do when we are awake.
Some of the oddities of dreams may be a manifestation of what happens when the brain makes metaphorical connections as we sleep. In waking life, we think in metaphors, knowing how to interpret them as metaphors. But when we think in metaphors during REM sleep, the brain can interpret those metaphors literally.
Charcot–Wilbrand syndrome (CWS) describes dream loss following focal brain damage specifically characterised by visual agnosia and loss of ability to mentally recall or "revisualize" images.
It is generally accepted that no-one can recall their birth. Most people generally do not remember anything before the age of three, although some theorists (e.g. Usher and Neisser, 1993) argue that adults can remember important events - such as the birth of a sibling - when they occurred as early as the age of two.
Adults can generally recall events from 3–4 years old, with those that have primarily experiential memories beginning around 4.7 years old. Adults who experienced traumatic or abusive early childhoods report a longer period of childhood amnesia, ending around 5–7 years old.
Thanks to fascinating research we now know that a lot goes on in babies' brains, including the ability to remember – starting in the womb.
