In the early s, neuropsychologist and psychoanalyst Mark Solms found that people who developed lesions in the white matter of their medial prefrontal cortex reported that they stopped dreaming. Dream recall can vary person to person, but it can also vary day to day for one person. Researchers have been studying dream recall for decades.
Even so, we don't know whether people who never remember their dreams actually dream less than people who frequently remember their dreams, or whether they are just forgetting their dreams more easily. People who have reported never remembering their dreams have been able to recall them when they are awakened at the right moment.
Many people have formed hypotheses about why remembering dreams is so notoriously difficult. Freud theorized that we forget our dreams because they contain our repressed thoughts and wishes, so we don't want to remember them anyway.
Other research points to the simple reason that other things get in the way. We are forward-thinking by nature, so remembering something when we first wake up is difficult. Dreams may be so hard to remember because the hippocampus , a structure in the brain responsible for learning and memory processes, is not fully active when we wake up.
This could result in a dream being present in our short-term memory, but not yet able to move to long-term storage. Some researchers believe that changing levels of the neurotransmitters acetylcholine and norepinephrine are part of the reason we forget our dreams. Others think that some dreams may just be too useless to remember, so the brain tends to discard them. And some scientists think that people with certain personality traits — like those who are prone to daydreaming and introspection — have less difficulty remembering their dreams.
Despite the unknowns around dream recall, there are some measures that we can take to increase the likelihood that we remember our dreams when we wake from our slumber. Those who believe we have a lot to learn about ourselves from our dreams are big proponents of dream journals. If you purchase something mentioned in this article, we may earn a small commission.

Go Paperless with Digital. 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.
If we could accurately identify colors, we would never make such mistakes. People may think they are more adept at identifying colors, however, because they tend to associate hues with specific objects, which do not change.
For instance, we will generally perceive an apple to be red because the light reflecting off its surface remains fairly constant from moment to moment. In contrast, in hearing we identify objects, people and speech by the changes in frequency.
