But having more white matter may not just help you remember your dreams, it may also promote dream creation. As prominent neuropsychologist Mark Solms found in the early s , people who developed rare, brain-damaging lesions within the white matter of the medial prefrontal cortex reported that they stopped dreaming altogether.
Another interpretation is that they stopped dreaming. But for most people, much of dream recall boils down to individual characteristics — some within our control, and some not. Scientists also know that women , on average, are more likely to remember their dreams than men.
Teenage boys are less encouraged to speak about their dreams or feelings. But both sexes may notice that their ability to remember our dreams seems to fade with age. As we grow older, our sleep patterns tend to change. Older people get less slow wave sleep, often referred to as deep sleep. Between the ages of 20 and 60, deep sleep decreases at a rate of 2 percent per decade.
But the amount of REM sleep, when our most memorable dreams seem to occur, stays about the same. Do age-related changes make much of a difference when it comes to dream recall? Vallat said probably not. Instead, day-to day stressors like deadlines, bills and appointments often take precedence over our dream worlds. And people may miss out on REM sleep by cutting sleep short. People who use alcohol and THC may also tend to forget dreams, as these substances are known to suppress dream-rich REM sleep, Vallat said.
Dream recall is simple if you ask Michael Schredl, a researcher at the Central Institute of Mental Health in Germany, who has studied a wide range of factors that can influence recall. All you need to do is set an alarm to sound every hour throughout the night.
Each time you wake up, ask yourself if you were just dreaming and then write it down. Register or Log In. The Magazine Shop. Login Register Stay Curious Subscribe.

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. Think of the all the dangers our prehistoric ancestors had to deal with, and it's clear that this response is important for survival.
So what can you do to help you remember your dreams? If something comes back to you, write it down or use a voice recorder to crystallize your thoughts. Are you happy, sad, or anxious?

Noradrenaline is a hormone that primes the body and mind for action, and our levels of it are naturally lower in deep sleep. Francesca Siclari, a sleep research doctor at the Lausanne University Hospital, says there are clear definitions between our states of wake and sleep — and that is no accident.

She says that people suffering from sleep disorders, such as narcolepsy, can find it difficult to tell the difference between their waking and sleeping lives, and this can leave them feeling confused and embarrassed.
It is no accident that the dreams we remember the most come from certain periods in our sleep cycle, affected by the chemicals coursing through our sleeping bodies.
We may find ourselves dreaming right before we wake up — but our morning routines actually get in the way of remembering the imagery. Often we are startled out of our slumber by an alarm clock, which causes a spike in our noradrenaline levels — thus making it harder for us to hang onto our dreams. Stickgold says he carried out a study some years ago where students in a lab were awoken shortly after they started entering this state.

So what if you actively want to remember your dreams? Obviously, each sleeper is different, but there are some general tips which might help you to hold on to your dreams. There are even more surefire ways to remember dreams, Stickgold says. Not three glasses of beer, because alcohol in an REM suppressant, but water. And there is another piece of advice offered by some sleep researchers — that simply repeating to yourself as you drift towards sleep that you want to remember your dreams means you wake remembering them.
Stickgold laughs.
