Dreams are still something of a mystery that scientific has no proof of resolving fully understood why or how we dream. The matter further complicated as everyone dreams, but some people never remember their subconscious adventures.
However, developments in brain imaging and recent physiological studies have brought us one step closer to answering the query of why some people remember their dreams more than others.
“There is no simple, definitive explanation, but there are a number of things that correlate,” Dr. Deirdre Leigh Barrett, a psychology professor at Harvard Medical School and author of The Committee of Sleep, said. He shared a few of the factors that can affect your dream recall.
Female, on an average, recall more dreams than men. It’s not 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.
It often gets harder to recall our dreams, as we get older. Your ability to memorise dreams improves in late childhood and adolescence, and tends to peak at twenties, Barrett says. After that point, people often experience a gradual drop-off in dream recall.
“More psychologically-minded people tend to have higher dream recall, and people who are more sensible and externally focused tend to have lower recall," Barrett says.
AMOUNT OF SLEEP
People dream every 90 minutes during the sleep cycle. However, those periods get longer throughout the night, meaning that you’re doing the most dreaming toward the morning—generally right before you wake up. So the more you sleep the more you dream.
According to a study, a part of the brain that processes information and emotions is more active in people who remember their dreams more often. 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 which makes you remember your dream.
