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. Why is that? We don't forget our daily actions that quickly.
“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.”
According to a poll done by CBS, 4 out of 10 adults under 30 say that they can remember their dreams the majority of the time. That is less than half of the young adults in the U.S. Younger people have better memory function than older adults, which is why forgetting dreams may scare some people.
Everyone dreams — even people who believe that they “never dream” and can't remember any of their dreams. That's according to a group of French researchers writing in the Journal of Sleep Research: Evidence that non-dreamers do dream. In questionnaire surveys, up to 6.5% of people report that they 'never dream'.

While every human being so far as we know exhibits REM sleep, not every human being reports dreams. It appears you can have REM sleep with very low dream recall or possibly without dreams entirely. There may even be groups of individuals who never recall their dreams or who do not dream.
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.
2. Light sleepers remember more dreams than heavy sleepers. Whether you remember dreams, then, depends on whether you are a light or heavy sleeper. A brain imaging study has found those who recall more of their dreams have higher activity in the medial prefrontal cortex (Eichenlaub et al., 2014).
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.
Women are more likely to report remembering their dreams than men, but there is a larger difference by age. Four in 10 adults under 30 say they remember their dreams at least most of the time. Americans over 30 are less likely to report remembering their dreams: more than a third say they rarely or never remember them.
Yes, depressed people tend to dream more. In fact, one study found that people who are depressed can dream up to three times more than people who are not depressed.
Most experts believe that lucid dreams are the rarest type of dreams. While dreaming, you are conscious that you are dreaming but you keep on dreaming. According to researchers, 55 percent of people experience these types of dreams at least one time in their life.
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.
The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes. People are more likely to remember the dream if they are awakened during the REM phase.
Lucid dreams are when you know that you're dreaming while you're asleep. You're aware that the events flashing through your brain aren't really happening. But the dream feels vivid and real. You may even be able to control how the action unfolds, as if you're directing a movie in your sleep.
“There's some evidence that, at times, sleep talking may be related to dreams, but this is not always the case,” Dr. Drerup explains. Most dreams happen when you're in the deep, rapid eye movement (REM) phase of sleep. But sleep talking can happen during any stage of sleep, including both REM and non-REM sleep.
As dreams are all about the self—your feelings and behaviors—if you're dreaming about a specific person in your life, then it's likely there's some aspect of them that is currently at work in your life, Loewenberg explains. Perhaps you both share a behavioral trait that is currently being activated.
Dreams feel real because we use the same brain to process them! Parts of the brain that process “real” sensory information in wakefulness are active in REM sleep. The more rational parts of our brain only switch on in wakefulness. This is why dreams play out like any “real” experience!
But have you ever had a dream with a person in it whom you have never seen before in your life? It may seem that way, but it is impossible. It is believed that the human brain is incapable of “creating” a new face.
Experiences during sleep qualify as dreamless if they lack the immersive character of dreaming. Examples are isolated or static visuospatial, auditory, or kinesthetic imagery lacking a clear hallucinatory context, movement sensations, and propositional thought (sleep thinking).
Although their visual dream content is reduced, other senses are enhanced in dreams of the blind. A dreaming blind person experiences more sensations of sound, touch, taste, and smell than sighted people do. Blind people are also more likely to have certain types of dreams than sighted people.
