Dreaming a New World | StoryPRO News

Everybody sleeps at night. Everybody dreams. And some people recall their dreams. But what is actually happening during dreamtime? And how does this mysterious phenomena impact our daily lives? To get a grasp on the subject, it's important to understand the science of sleep.

During a typical night's rest, people go through four to five 90-minute sleep cycles, and each cycle consists of four individual stages of sleep. An easy way to ensure waking up refreshed is to try to wake up at the end of a cycle, not in the middle. For example, getting 6, 7.5, or 9 hours of sleep would each be at the end of a cycle.

It is a common experience that a problem difficult at night is resolved in the morning after the committee of sleep has worked on it.

Sleep and regular sleep-wake cycles are critical in regulating the development of various hormones and getting enough deep sleep is critical for maximizing strength training gains and regenerating cells to repair tissue and bone, as well as stimulating blood flow to muscles for recovery. In fact, deep sleep is responsible for the production of 95 percent of growth hormone.

According to the National Sleep Foundation, it is recommended that teenagers get 8–10 hours of sleep per night, 7–9 hours for adults (18–64), and 7–8 hours for older adults (65+).

Studies show that sleeping less than 6 hours a night increases mortality and health outcomes such as diabetes, cardiovascular disease, coronary heart disease, and obesity.

On the other hand, sleep duration of over 9 hours has been correlated with more significant mortality and increased mortality, diabetes mellitus, cardiovascular disease, stroke, coronary heart disease, and obesity

Overall, consensus assessments of over a thousand scientific articles have revealed that the sweet spot for most people is ideally between 7 and 7.5 hours.

Education is the kindling of a flame, not the filling of a vessel.

As we go about our day, we constantly experience and adapt to the world around us, learning and growing. Our experiences continually shape our worldview, and our brains are continuously changing as a result.

Research suggests that sleep helps learning and memory in two distinct ways. First, a sleep-deprived person cannot focus attention optimally and therefore cannot learn efficiently. Second, sleep itself has a role in the consolidation of memory, which is essential for learning new information.

New events become electrical impulses that spread through the hippocampus's neural networks, an area of the brain responsible for the formation of new memories. These impulses, or new memories, change synaptic connections, making some more potent and others weaker.

For something to become a memory, three functions must occur:

Neurons oscillate between a depolarized on-state when they fire and a hyperpolarized off-state when they are silent during deep non-REM sleep. A recent study found that opposing brain waves known as delta and slow-oscillation serve two distinct functions during this down-regulation. Delta waves inhibit memory formation, while slow-oscillation waves do the encoding.

A recent study found that language learning can be enhanced during slow-oscillation wave periods. The study showed that at the peak of these slow-oscillation waves, word associations are registered and encoded. On the other hand, research has shown that delta waves proliferate in brains with amyloid plaque buildup, a hallmark of Alzheimer's disease.

When awake, learning occurs. When asleep, sorting and processing occur based on relevance and future expectations of usefulness so that essential memories are easier to retrieve for future use.

The brain has a more difficult time absorbing and recalling new information when it lacks adequate sleep. According to research, better sleep quality, duration, and consistency are all linked to higher academic performance.

The future belongs to those who believe in the beauty of their dreams.

Dreams are most common during REM sleep, but they can occur at any stage of sleep. Non-REM and REM sleep dreams, on the other hand, appear to follow different patterns.

REM dreams are more imaginative, immersive, and nonsensical, which enhances the integration of unassociated information for creative problem-solving.

This fluid interpretation is at the heart of a creative mind while dreaming, working without rules to create and imagine the unimaginable. Many of the world's most significant inventions and discoveries were inspired by ideas and inspirations that came to them in their dreams.

In 1619, a young soldier stationed in Germany had three dreams involving spirits, including an evil spirit and the holy spirit. That soldier was Rene Descartes, and those dreams gave rise to dualism.

In 1845, Elias Howe invented the sewing machine. He had been thinking about making a device with a needle that would go through cloth, and he had a dream that provided some newfound inspiration. In his dream, Elias was surrounded by cannibals who were about to be cooked and eaten. While observing them dance around a fire with spears moving up and down, he noticed a hole at the tops. When he awoke, he realized that a hole in the needle close to the point, rather than the other end, provided the solution he was looking for, making the mechanical sewing machine a technological possibility.

In 1953, a young molecular biologist had a dream involving a spiral. That spiral served as an inspiration for the discovery of DNA's double-helix structure. Imagination and creativity are inextricably linked, and human progress is directly proportional to both.

I used to have a lot of trouble sleeping, but I began researching why it's important to get enough sleep. This article solidified that. I never knew that mortality rates went up if you didn't get enough sleep. I am going to try eliminating blue light from my bedroom more at night now. I am also going to install some air conditioners. I already grabbed some blackout curtains to ensure that it's dark enough for me to hopefully get some uninterrupted sleep, there is a street lamp right outside of my house and the light used to shine directly into my bedroom window. Another great read, thank you!

Reading this article because I’ve been researching the importance of sleep and reasons why adults might be having trouble sleeping. Somebody close to me in my life has expressed how they have a hard time sleeping at night and it affects them during the day making them tired and groggy. I also know this person does drink a couple beers every day it was interesting to find the correlation between how alcohol affects your sleep every night or by drinking too much makes you feel like you fall asleep good but will actually cause you to have a poor nights sleep. Getting enough sleep is so important to your health and I know having this further knowledge will help my friend in making better lifestyle choices.

Interesting piece! I have always wondered about the origins and purposes of sleep and dreams. I often find myself having the more imaginative, immersive, and nonsensical dreams you described, so it is fascinating to see how this might improve my creative problem-solving ability. There is no doubt sleep is important in everyday life.

Great information here on sleep in general, but especially dreams. I've been getting more and more interested in dream analysis!

It wasn't until the passing of both of my parents (right after the other) that I appreciated and understood the importance of dreams. Both of my parents suffered from chronic illnesses that eventually took their lives. When they were each in the hospital, and after each of them passed, I remember dreaming of them quite often. I still do. Sometimes the things they say in my dreams include advice or things that I wish they had told me in the past, and they represent part of my thoughts that happen to be on my mind when I go to bed. Maybe they are trying to reach me from the other side, or maybe it's my own subconscious and my conscience working together to get me to look at something in a different way. Either way, I've always believed in the power of dreams and how they help me function in the waking hours of the day.

This article really resonated with me because last night I had the most vivid dreams and I was very interested in reading about the different stages of sleep today. I’ve probably learned about this before but I forgot all about it. I wish I would have life-changing dreams like some other famous people mentioned in the article but I usually have the most straightforward dreams. Last night I dreamt I was buying furniture for our addition and discussing prices with the company. No need to figure that out because it’s probably what I’m going to do in the next month. Interesting to read about adults my age and how much sleep they need maybe I do need to get some more sleep! Good to know.

I have always been a big believer in 8-10 hours each night. I will never forget one of my favorite musicians from the band Y&T saying "He always gets at least 8-10 hours and he is in his 70's looking amazing!

Most people I know that only get 6 hours or less look their age.

I didn't know that muscles are paralyzed to prevent the legs and arms from flailing in response to consciousness and the dream experience.

Thanks for sharing!

Hey Leonid, I think that it's interesting you mention that because I definitely agree with Jung. I don't think that all dreams are even necessarily nonsensical, but an experience in a higher realm that we have yet to understand. There are so many more encounters where we have discovered some of the biggest mysteries in life just by dreaming . I've been getting more into lucid dreaming lately so this was a great article to read on how I could deepen my sleep even more.

Thank you for taking your time to write this. It's an interesting contrast to Jung's view of dreams, where they are seen as attempts of psyche to balance itself.

"Jung felt that the psyche sought balance, much like the concept of entropy from the field of physics. Entropy, in simple terms, is a thermodynamic principle that all energy within a system (including the universe) will eventually even out. "
