The opportunity to tell you about the latest interesting content shared by members of Echosciences. Find all the chronicles in this folder or on the RCF-Isère site !

The chronicle of April 7, by Virginie Strohmeyer, in sound and in text below:

On RCF Isère, it’s time to find the Media Echo with Virginie Strohmeyer, intern in scientific communication at La Casemate. You are going to present to us the latest news from Echosciences Grenoble.

Hello Virginia!

Hello Nicolas !

Today you are going to tell us about dreams.

That’s right. I found it interesting to talk about this difficult state to study: the dream! We don’t really know why or how we dream. And some scientists are looking into the matter to understand the nature and function of dreams.

As a reminder, there are 5 stages in our sleep: falling asleep, slow or restorative sleep, light slow sleep, deep slow sleep and paradoxical sleep. It’s in the REM sleep let our dreams flow. They come from our auditory, visual, gustatory and olfactory memory and from our emotions.

And then imagine that some people are able to act as they please in their dreams. This is called lucid dreaming!

Are these people aware of being in a dream?

Absolutely ! They are aware of this and can even freely interact with characters, actions or places. They can modify, create or change the course of history as if nothing had happened. About 20% of people would experience this lucid dreaming state every month and only 1% would have several such experiences every week.

Can anyone lucid dream?

Yes, and there are methods to access lucid dreams. There is, for example, the reflexive-critical attitude, which consists in getting into the habit of asking oneself whether one is dreaming or not. Once this habit has been taken, it is possible to ask yourself the question during your dream.

The MILD method, for “Mnemonic Induction of Lucid Dreams”, is to convince yourself that you are going to have a lucid dream. The goal is to convince yourself that it will happen to increase the chances of entering the lucid dream state. Another method that I find interesting is the DILD method, for “dream initiated lucid dream”. Its objective is to notice unreal elements in order to become aware that one is in a dream.

But why have lucid dreams?

If you’re prone to nightmares, it might be worth learning lucid dreaming techniques to choose whether to wake up or make your nightmare less distressing by altering the narrative.

Researchers have asked themselves the question of using this state to stimulate creativity, learning or problem solving. For example, an English comedian by the name of Dave Green, during the Covid-19 pandemic, went back to having lucid dreams to… create works of art in his sleep and redraw them when he woke up!

Is it possible to communicate with dreamers?

Well, an experiment was conducted by scientists with lucid dreamers. In the waking phase, the researchers trained them using sound and light signals combined with an instruction to become lucid.

These sounds and lights were then used during their sleep to encourage them to be aware of their thoughts and sensations in their dream. Result: The researchers used the participants’ eye movements to ask them simple mathematical questions like 8 – 6. The participants answered successfully.

Thank you Virginie for this amazing information on sleep and our dreams! Before leaving us, an event to share with us?

Well, if you want to know if robots dream too, you can come to the Casemate Cult Evening this Thursday, April 7, from 8:30 p.m.! We will dive into the heart of the matrix for an evening around artificial intelligence and pop-culture!

Well the appointment is made! See you soon Virginia!

See you soon
