Particularly memorable dreams may create an impression that persists for decades. Recounting the dream to another person may help to stabilize the memory. Dreams or nightmares that are associated with intense emotions, including fear, may also stick in the mind. The amygdala is an area of the brain that may help to elicit these emotion-laden dreams. It is more likely that dreams will be remembered if your state of REM sleep is fragmented.
Alarm clocks notoriously interrupt REM sleep towards morning. It is possible to fall back asleep and to re-enter the same dream experience repeatedly. Sleep disorders may impact dream recall.
Untreated obstructive sleep apnea may also contribute to fragmented REM sleep as disturbed breathing occurs due to relaxation of the airway muscles. For some, this may lead to increased dream recall including dreams of drowning or suffocation. People with narcolepsy also experience sudden sleep transitions that contribute to dream recall, sleep-related hallucinations, and sleep paralysis. Poor sleep habits, stress, and psychiatric conditions may also fragment sleep and increase dreaming and recall.
If you are interested in improving your dream recall, consider a simple change: keep a dream journal. By keeping a pen and a notebook on the nightstand next to the bed, it becomes easy to quickly record dreams immediately upon awakening, before they have had a chance to fade.
Writing down your dream may encourage improvements in dream recall. If the scribbled notes can be interpreted later in the morning, it may be possible to reflect on the meaning of your dreams. Dreams are a fascinating part of sleep. Though you may feel distressed by not remembering dreams, rest assured that this state of sleep is likely still occurring. The benefits yielded, from memory processing to learning and problem solving, are likely just below the surface of awareness.
As you fall asleep, imagine a world that might be, and it may come to you in the night. Ever wonder what your personality type means? Sign up to find out more in our Healthy Mind newsletter.

Most of us have 4 to 6 dreams a night, but we forget the vast majority of them. Dreams tend to occur during the rapid eye movement REM cycle of sleep. A study noted that our ability to make memories is impaired during REM sleep. Missing out on REM sleep could mean missing out on dreams, too. Poor sleep can be a consequence of a health problem or a contributing factor in one. Sleep disorders, such as insomnia and sleep apnea , can keep you from entering the REM sleep cycle.
Insomnia can increase your risk for:. Among adults with depression , up to 90 percent report trouble sleeping, and insomnia is the most common complaint. That could account for fewer or less-memorable dreams. But depression may also increase disturbing dreams or nightmares. Sleep problems are highly prevalent in people with bipolar disorder. Sleep problems may lead up to an episode of mania or depression. Between 69 and 99 percent of people experiencing a manic episode experience sleep disruption such as needing less sleep or having trouble falling asleep.
Insomnia can be a risk factor for developing anxiety or a result of anxiety. Sleep problems are reported by people who have:. Although lack of REM sleep can cut down on dreams, people with anxiety are more likely to have scary dreams.

Discover World-Changing Science. ALTHOUGH MOST of us believe we are better at identifying colors than sounds, our ability to identify the exact frequency of light associated with a color is actually no better than our ability to name a pitch. Our perception of visible light depends on context.
You might go shop-ping for house paints, for example, and be shocked to find that the particular shade of white you selected in the store makes your kitchen look pink! You may have chosen the wrong shade of white because the ambient light in the store differs from that of your home.
