10 curiosities about dreams revealed by science

When we sleep too somiem. At least in certain specific phases of sleep, in which we imagine unreal situations, Product of our unconscious. These dreams can be emotional, magical, or weird, and can even be frightening, like nightmares.

Although psychoanalysis has long provided the basis for the interpretation of dreams, scientific research in the dream world has not yet been able to determine exactly why we dream or what causes us to dream certain things in particular.

On what (little) we already know about them we leave here 10 curiosities about dreams discovered by science.

10 curiosities about dreams revealed by science

Various scientific research leads us to different conclusions about the dream world. Let’s get to know them. Let’s get started!

1. We dream, on average, more than 6 years in our life

Since our birth, we dream. Everyone dreams: it’s a common thing in our species, and in case you were wondering, also dream those who say they don’t (They just don’t remember dreams, but that doesn’t mean they aren’t dreaming). Research shows that we dream at night in periods of 5 to 20 minutes.

Adding up all these small periods over a half-life, we can say that we have spent about six years dreaming.

2. Most dreams are quickly forgotten

Sleep scientist Allan Hobson has revealed, based on his multiple studies on the subject, that up to 95% of dreams are quickly forgotten, A few minutes after waking up.

Then you need to ask: Why is it so difficult to remember the content of dreams?

The explanation has been found in different experiments. It seems that the changes that take place in the brain during the hours we dream of do not match the way we regularly process information to deliver information to memory. Brain scans of people who sleep for many hours at night have shown that the frontal lobes, areas of the brain that play a key role in the formation of memory and memories, remain inactive during the night. MOR phase of sound, Just when we are dreaming.

3. Men and women: different ways of dreaming

Several studies have found some differences in the way women and men dream. Above all, the differences lie in content of dreams.

We see that men report more cases of dreams in which scenes of aggression are experienced. Women, on the other hand, tend to have slightly longer dreams, and a little greater complexity (more details, characters, situations …). As for who appears to us in dreams, men dream of other men twice as often as women. They dream of characters of both sexes.

4. Some dreams are black and white

about eight out of ten dreams are “in color”But there is a small percentage of the population that claims to dream without colors, that is, in black and white.

In research that investigated the issue of color in dreams, experimental subjects had to select colors that matched the dream they just had on a chart, and soft pastel colors were most commonly used. So it seems that we tend to dream in pastel tones.

5. Do animals dream? Everything indicates yes

Many people have seen their pets move their tails, legs or mouths while they sleep. The explanation for these movements may be that animals dream too, although the fact that animals dream is a difficult hypothesis to prove. Researchers believe they are dreaming and even dare to say that they, like humans, go through MOR and not MOR sleep stages.

One of the scientific proof that dreams are due to the study of a gorilla mastering sign and sign language. At one point, while asleep, he gestually communicated certain images of what he was dreaming of.

6. Can sleep be controlled? Lucid dreams

Have you heard of it lucid dreams? This is the phenomenon that occurs when, despite sleep, we are aware that we are dreaming. Those who have experienced this kind of dream are able to control and guide the content of sleep.

About 50% of the population remembers having experienced a lucid dream at least once in their life. There are even some people who have the ability to control their dreams quite regularly.

7. Negative emotions are more common than positive emotions in dreams.

One of the leading representatives of sleep research, Calvin Hall, has recorded more than 50,000 student dreams over half a century.

This vast archive of dreams revealed many of the emotions and sensations we experience during sleep, such as joy, fear, anger … But the emotion most often observed was anxiety and, in general , negative emotions (Fear, despair, sadness) predominate over positive emotions.

8. The blind dream too

The blind, although they cannot see, also dream. Blind people who have gone blind at some point in their life have the ability to read pictures and visual content in your dreams.

In the case of people who are born blind, their dreams are a little different: they represent dreams through other senses, such as smell, hearing or touch.

9. Women also dream of sex

Research has found that, contrary to popular belief, women dream of sex as much as men.

However, it seems that the situations described in male and female dreams they vary a little: Women dream of famous men, while men report more dreams in which they have sex in arousing situations.

10. There are dream contents that we all dream of (universal dreams)

Some dreams are common to all humans. Many dreams are influenced by each person’s personal experiences, but still strange, researchers have revealed that there are certain recurring themes in our dreams, regardless of cultural differences.

For example, it seems that everyone dreams of being persecuted, being attacked, or falling into the void. other universal dreams are the experiences in the school setting, the fact of feeling still or the embarrassment of being naked in public.
