History of Wolves and Dogs | Documentary for Sleep
#116
Yesterday at 4:30 PM

In this sleepy story, we trace the shared history of wolves and dogs, from their ancient evolutionary origins to the deep bond they formed with humans through domestication. We explore how wolves live, communicate, and organize their social world, and how, over thousands of years, some of them evolved into the many dog breeds we know today. Along the way, we see how dogs developed their unique emotional connection to us—a bond that has made them one of our closest and most devoted companions.

Nature Sleep Story: Wonder of Trees

I also discuss the life cycle of trees, their composition, and many often unnoticed aspects, such as their ability to exchange signals, connect by their roots, develop mutualistic relationships or adapt to different environments. We also review extraordinary trees: Hyperion, the t...


The Myth of El Dorado

In tonight's story, I take you on a historical tour of the myth of El Dorado. I discuss what the early years of the Spanish conquest of America were like, how the encounter between older European legends and the reality of pre-Columbian America created new myths about fabulous places, and some of the expeditions that went on a search for El Dorado or the Cities of Gold, to the Andes Mountains, the Amazonian forest or New Mexico.

History of Rooms in Homes - Documentary and Sleepy Story
#101
12/14/2025

In tonight's sleep-inducing episode, I invite you to an overview of rooms since humankind started to build homes. For much of our history, most people lived in single-room dwellings and multiple-room homes were a privilege for the happy few. This started to change after the 16th Century, and rooms multiplied for almost everyone, often influenced by aristocratic and bourgeois homes. From medieval long houses and manors to aristocratic apartments, parlors or drawing rooms to living rooms and modern bedrooms, we have a lot to discover!

Mysteries of Consciousness: why do we know we exist?
#100
12/07/2025

What is this subjective experience, this awareness of existence, that we call consciousness? In tonight's episode, we will examine some of the aspects of this philosophical, scientific, and spiritual question. Is consciousness a binary thing, or is it a kind of continuum with different "levels"? Do animals experience a degree of consciousness and how can it be inferred or measured? Is it reducible to biology, is it the product of the treatment of information, is it something immaterial and detached from the physical world? Could an AI acquire consciousness from a silicon substrate, and if yes, what would be...

History of Byzantium
#98
11/23/2025

In this sleep documentary, I take you to the mythical city of Constantinople to explore the history of the Byzantine Empire. As the Western Roman Empire collapsed under invasions, its Eastern counterpart lived on and perpetuated the dream of recreating the Roman Empire during the Middle Ages.

History of Monasteries and Monasticism | History for Sleep

Faust and History of Pacts with the Devil
#94
10/26/2025

The "pact with the devil" is a cultural motif that keeps coming back in stories. The legend of Faust is a good example, but not the oldest: it took inspiration from other stories, such as the legend of Theophilus. In this episode, I tell you some of these stories. We will also discover the real, historical figures that inspired them (Theophilus, Johann Faust, Pope Sylvester II, Saemundr Sigfússon...), and the firm belief in the existence of such pacts, that were often invoked in witchcraft trials from the Middle Ages to the Seventeenth Century. As an example, I tell y...

In tonight's episode, we take a look at three topics that keep sparking debates in their respective scientific communities: 

• The existence of supermassive black holes at the center of galaxies, which are several million times more massive than "regular" black holes born from supernovas. Did these gigantic black holes appear as such, did they become so big by absorbing other bodies for billions of years, or is it something else?

In this soft-spoken bedtime story, I tell you about the concept of "generation ships": large spacecrafts that would transport dozens, hundreds, or even thousands of people to faraway destinations in the galaxy, over several generations. Even though we are nowhere near seeing one, the technical, biological, and social aspects of such a project are fascinating. So, I review them to explain the main challenges and what possible solutions could be found.
