WTF Fun Fact 13698 – Dream Recall

When sleep is fragmented or of poor quality, people often have better dream recall. In other words, they have a higher frequency of remembering their dreams.

The Link Between Sleep Quality and Dream Recall

Sleep comprises multiple cycles, each consisting of stages including REM (Rapid Eye Movement) and non-REM sleep. REM sleep is most closely associated with vivid dreaming. Typically, a night of uninterrupted sleep allows for several cycles of REM, with the longest and most intense periods of REM sleep occurring in the latter part of the night.

Poor sleep quality, characterized by frequent awakenings or prolonged periods of wakefulness, disrupts this cycle. When sleep is interrupted, especially during or right after REM phases, individuals are more likely to remember their dreams. This is because waking up during REM sleep provides a direct bridge from the dream state to wakefulness. This makes it easier to recall dreams.

Factors Contributing to Dream Recall

Several factors can contribute to poor sleep quality and, consequently, increased dream recall:

  • Stress and anxiety can lead to restless nights and more frequent awakenings. This increases the chances of waking during REM sleep.
  • Lifestyle choices, such as consumption of caffeine or alcohol before bedtime, can disrupt sleep patterns. This leads to more fragmented sleep.
  • Sleep disorders, such as insomnia or sleep apnea, inherently lead to poor-quality sleep and can thus enhance recall.

Psychological and Cognitive Implications

Increased dream recall due to poor sleep quality is not merely a curiosity but has implications for psychological and cognitive well-being. High recall can sometimes reflect the presence of stress or anxiety, as the mind processes emotional experiences during sleep.

Moreover, consistently poor sleep quality, and the consequent frequent dream recall, may impact daytime functioning by affecting mood, concentration, and overall cognitive performance.

Managing Dream Recall and Sleep Quality

For those interested in managing their dreams—whether to remember more dreams or to reduce the impact of disturbing dreams—addressing sleep quality is key.

Establishing a regular sleep schedule, creating a relaxing bedtime routine, and minimizing sleep disturbances can help promote more restful, uninterrupted sleep. For individuals dealing with stress or anxiety, relaxation techniques or professional support may improve sleep quality and reduce the intensity and frequency of remembering one’s dreams.

WTF Fun Fact 13285 – How Blind People Dream

Have you ever wondered what blind people experience in their dreams? You’re not alone – the question of what blind people dream has intrigued researchers for years. More specifically, the question is about the dreams of those who have been blind since birth. These are people who haven’t collected visual images to fuel their dreams.

According to The Conversation (cited below):
“Humans born without sight are not able to collect visual experiences, so they understand the world entirely through their other senses. As a result, people with blindness at birth develop an amazing ability to understand the world through the collection of experiences and memories that come from these non-visual senses.”

Insights into how blind people dream

People who are born blind do dream, despite having never seen visual images. But their dreams seem to be different from those of sighted individuals. For example, instead of visual images, blind people may experience dreams that involve more vivid sensory experiences, such as sounds, smells, and touch.

The article in The Conversation by neuroscientist John J. Foxe and psychologist Andrei Gorea notes, “the visual areas of the brain are not dormant during dream sleep in congenitally blind people, but instead get co-opted for processing other senses.” This means that while blind people may not see images in their dreams, their brains are still processing sensory information. And they do this in much the same way that sighted people process visual information.

One study conducted by the University of Copenhagen found that blind individuals may have more intense and emotional dreams than sighted individuals. That’s because their brains may compensate for a lack of visual stimuli by enhancing other sensory experiences. As Foxe and Gorea explain, “this is thought to be due to the fact that the brain has to work harder to create a sensory-rich environment in the absence of visual input.”

The study also found that people who were born blind may dream more about other people and interpersonal interaction. That makes sense since blind people may rely more heavily on senses like hearing and touch to interact with others. Foxe and Gorea note that “this may result in a greater emphasis on interpersonal relationships in dream content.

Seeing dreams

Interestingly, some blind individuals really do seem to dream in visual images. This phenomenon is called “sighted dreaming.” It has been reported by some blind individuals, and researchers hypothesize that it may be related to the brain’s innate ability to construct mental images based on experiences.

There’s still a lot we don’t know about the dream experiences of those who have been blind since birth. But research has given us fascinating insights into how the brain processes sensory information and uses it during dream sleep. Foxe and Gorea note: “…this research has implications…for our understanding of how the brain adapts to sensory deprivation more generally.”

Overall, the dream experiences of blind individuals continue to intrigue us. As our understanding of the brain and its functions continues to evolve, we may discover even more fascinating facts about the dream experiences of blind individuals and how they differ from those of sighted individuals.

WTF Fun Fact 12739 – The Dreams of Men

Multiple studies have shown tend to have more male characters in their dreams.

We have very little control over what we dream about, even though many of us try to direct our dreams. (I know I do – if I could spend all night dreaming about being a wealthy villa owner on an abandoned tropical coast instead of reliving a made-up scenario about missing a vital exam and never graduating high school, I would!)

Studying dreams

Anyway, there are hundreds of studies on dreams. Most of them involve having people use dream journals where they write down the contents of their dreams any time they awaken. The journals are then processed by a researchers who looks for certain characteristics without knowing anything about the person the journals belong to (that’s why they’re called a “blind judge” in many research papers).

Researchers usually start with common themes and types of characters and count mentions of them. And a lot of the research has backed up the data we’ve collected over time. (However, there are some differences between cultures as to what we dream about.)

Demhoff’s dream research

For example, G. William Domhoff wrote one of the most widely-cited papers on the genders we dream about (nearly two decades ago, before talking about more than two genders was a cultural priority). It’s called “The Dreams of Men and Women: Patterns of Gender Similarity and Difference,” and it was published in 2005.

In the paper, Domhoff is very clear that “The study of gender similarities and differences in dream content has proven to be a dangerous mine field for dream researchers.” That’s because this kind of information has the “potential to stir up all the tensions that inevitably accompany any discussion of gender in a world where gender discrimination–and conflicts between men and women on many personal issues–are pervasive.”

Limited interpretations

In other words, it’s likely that a large number of people will dislike this “fun fact” because they somehow feel judged by it or don’t like whatever they think it implies (which is largely nothing).

Demhoff was also careful to not that variations across cultures and across genders make generalizations difficult. He’s just reporting on one characteristic that he found to be statistically significant – the gender of the characters in people’s dreams.

Demhoff concentrated on American subjects since he was most familiar with the cultural characteristics of Americans. But other researchers have studied other cultures and found some key differences.

To make sure everyone is categorizing things in a roughly similar way, Demhoff used a coding system developed in 1966 called the Hall/Van de Castle system, where most things fall into pretty simple categories like: men/women; indoor setting/outdoor setting, etc. But that system was created based on the dream journals of white, middle-class college students at Case Western in the 1950s and 60s. In general, other studies have found these categories useful too.

So, on to the results (because results don’t mean much without some context first!).

What men dream of

Demhoff asked what percentage of dreams had a negative element “such as aggressions, misfortunes, failures, and negative emotions (anger, apprehension, confusion, and sadness)…” And the results were that “men and women are similar in that 80% of men’s dreams and 77% of women’s have at least one of these negative elements.”

When it comes to positive aspects, “such as friendly interactions, good fortune, success, and happiness, 53% of dreams for both men and women have at least one of those elements. Men and women also have an equal number of dreams in which food or eating is mentioned–about 17%.”

In addition, “Both men and women are more often victims than aggressors in the aggressive interactions in their dreams, and they face the same attackers, namely, men who are not known to them (“male strangers”) and animals. On a more positive note, both men and women are equally likely to befriend another character in their dreams.”

But we started with the most reported-on finding, which is that “men dream twice as often about other men as they do about women (67% vs. 33%), and women dream equally about both sexes (48% men, 52% women).”

What’s implied by the dreams of men? Not much

And here’s where people get offended. No one is implying that men fantasize about other men. They can be someone you fight on the street, your 5th grade math teacher, your dad…whatever.

Women may also have more of a character gender balance because their dreams tend to have more characters overall. This may be a result of women’s dreams being longer overall than men’s.

But Demhoff points out that this in not universal. Even among Black Americans, men and women tended to have an equal gender breakdown in dreams. Studies of Mexican and Peruvian teens as well as German college students also showed more of a gender balance. However, in each case there were slightly more men than women in everyone’s dreams.

WTF Fun Fact 12725 – Ancient Stone Pillows

It’s hard to find a good pillow. And while some of us like our pillow firm, it would take a major adjustment to sleep like ancient Mesopotamians and Egyptians (well, in more ways than one, I suppose).

Here’s one of the most famous pillows in history, brought to you from Egypt King Tut’s tomb:

One of 8 headrests found in Tutankhamun’s tomb. The god of air, Shu, is carved in ivory. The piece resides in the Egyptian Museum in Cairo.

It’s beautiful, but it lacks the kind of functionality we typically look for today.

Until the Industrial Revolution, pillows weren’t even a household object. Yes, some ancient Greeks and Romans did stuff straw in cloth to lay their heads on, but a pillow is also a symbol of having excess lying around to use for more practical purposes. However, we can credit the Greeks with bringing us closer to the era of the soft pillow.

However, in ancient Mesopotamia, China, and Egypt, wealthy people would elevate their heads on “pillow” made of stone (or ivory – or another luxury material). They were designed to keep insects out of their ears, noses, and mouths – and probably to maintain a good hairstyle every now and then.

We’ve also found some pillows that are beautifully engraved with messages about keeping away bad spirits as well, but it’s unclear how those would be fooled by an elevated head. Still, it gives us a good idea of what ancient people were concerned about when they laid down their heads at night. — WTF fun facts
