6 Factors That Determine Whether or Not You Remember Your Dreams
Within the scientific community, dreams are still something of a mystery. Many experiments have been conducted and many theories have been put forth, but researchers still don’t fully understand why or how we dream. Further complicating matters is the fact that everyone dreams, but some people never remember their subconscious escapades.
However, improvements in brain imaging and recent physiological studies have brought us one step closer to answering the question of why some people remember their dreams more than others. There’s no simple, definitive explanation, вЂњbut there are a number of things that correlate,вЂќ Dr. Deirdre Leigh Barrett, a psychology professor at Harvard Medical School and author of The Committee of Sleep, tells Mental Floss. Barrett shared a few of the factors that can affect your dream recall.
Women, on average, recall more dreams than men. Researchers aren’t exactly sure why, but Barrett says it could be a biological or hormonal difference. Alternatively, women might be more cognizant of their dreams because they tend to be more interested in dreams in general. However, Barrett notes that differences between men and women in regard to dream recall are вЂњmodestвЂќ and that there are greater differences within each sex than between the sexes. In other words: There are plenty of women with low dream recall and plenty of men with high dream recall.
As we get older, it often gets harder to recall our dreams. Your ability to remember dreams improves in late childhood and adolescence, and tends to peak in your twenties, Barrett says. After that point, people often experience a gradual drop-off in dream recall. However, there are exceptions, and people sometimes experience the opposite.
Again, this is by no means a prescriptive rule, but there seems to be a correlation between certain personality traits and high dream recall. “More psychologically-minded people tend to have higher dream recall, and people who are more practical and externally focused tend to have lower recall,” Barrett says. In addition, better dream recall has a вЂњmild correlationвЂќ with better recall while completing certain memory tasks during waking hours,В according to Barrett.
4. AMOUNT OF SLEEP
The amount of sleep one gets on average is one of the most important factors related to dream recall. People dream every 90 minutes during the REM (rapid eye movement) sleep cycle. However, those REM periods get longer throughout the night, meaning that you’re doing the most dreaming toward the morningвЂ”generally right before you wake up. If you only sleep four hours instead of eight, you’re only getting about 20 percent of your dream time. For this reason, some people report remembering more of their dreams on the weekend, when they have the chance to catch up on sleep.
5. BRAIN ACTIVITY
Thanks to brain imaging, scientists now have a better idea of which parts of the brain are associated with dreaming. A part of the brain that processes information and emotions is more active in people who remember their dreams more often, according to a 2014 study. This region toward the back of the brain, called the temporo-parietal junction (TPJ), may help people pay more attention to external stimuli. In turn, this may promote something called instrasleep wakefulness.
“This recallers are more reactive to environmental stimuli, awaken more during sleep, and thus better encode dreams in memory than low dream recallers,” Dr. Perrine Ruby told the International Business Times. “Indeed, the sleeping brain is not capable of memorizing new information; it needs to awaken to be able to do that.”
Higher activity in the TPJ and another region of the brain called the medial prefrontal cortex (MPFC) might also “promote the mental imagery and/or memory encoding of dreams,” researchers wrote in the study’s abstract.
More recently, in 2017, researchers discovered that high dream recall is also linked to higher activity toward the front of the brain. The pre-frontal cortex is the part of the brain that deals with abstract thinking, so it makes sense that it has been linked to dream recall and lucid dreaming (being aware that one is dreaming), Barrett says.
6. RESPONSE TO EXTERNAL STIMULI
In a similar vein, people who remember their dreams more frequently also tend to exhibit more brain activity after hearing their name spoken aloud while they’re awake, according to a 2013 study. Upon hearing their names, a group of вЂњhigh recallers,вЂќ who remember their dreams almost every night, experienced a greater decrease in a brain wave called the alpha wave than a group of вЂњlow recallers,вЂќ who remember their dreams once or twice a month. This decrease in alpha waves is likely preceded by an increase in brain activity upon hearing their names. Essentially, people with greater dream recall tend to experience activity in more regions of their brain in response to sounds. According to Barrett, there may be an evolutionary explanation for this.
вЂњEvolution wants us to get restorative sleep but it also wanted us to wake up to danger and check it out and be able to go back to sleep quickly afterwards,вЂќ she says. Think of the all the dangers our prehistoric ancestors had to deal with, and it’s clear that this response is important for survival. In essence, high recallers are вЂњprobably just a little more aware and watching during their dream, and that helps make it a long-term memory.вЂќ
So what can you do to help you remember your dreams? It may sound simple, but before you go to bed, think to yourself, вЂњI’m going to remember my dreams tonight www.besthookupwebsites.org/polish-hearts-review.вЂќ The very act of thinking about dreaming can make a big difference.
вЂњYou could say that just reading this article is somewhat more likely to make you recall a dream tonight,вЂќ Barrett says. вЂњPeople who are taking a class on dreams or reading a book on dreamsвЂ”any short-term intervention of paying more attention to themвЂ”tends to create a short-term blip in dream recall.вЂќ
When you first wake up, don’t do anything except lie in bed and try to recall any dreams you had. If something comes back to you, write it down or use a voice recorder to crystallize your thoughts. Dreams are still in your short-term memory when you wake up, so they’re fragile and easy to forget.
If you don’t remember anything, Barrett says it’s still helpful to assess how you feel when you first awaken. Are you happy, sad, or anxious? вЂњSometimes if you just stay with whatever emotion or little bit of content you woke up with,вЂќ she says, вЂњa dream will come rushing back.вЂќ
