William was nine years old when he stopped running in the middle of the garden.
The other boys kept shouting after the ball, their shoes scraping over the gravel in the schoolyard in Lyon. But William stood still, his right hand open in the air as if he had bumped into something invisible. It wasn't pain. It wasn't fear. It was as if someone had pressed their palm against his—on the other side of glass he couldn't see.
It lasted three seconds. Maybe less.
When he came to, the teacher was already calling his name. William blinked, looked at his own hand, and slowly closed his fingers, as if trying to hold on to whatever had touched him.
That night, lying in the dark bedroom of the apartment in the sixth arrondissement, he stared at the ceiling. His mother had left the door ajar, and the hallway light drew a golden stripe across the floor.
He couldn't explain it. But he knew he wasn't alone.
Not in the bedroom. Not in the house. Somewhere nameless, someone existed alongside him.
By the time he was fourteen, William had already learned not to talk about it.
He had tried once, when he was eleven, during dinner. He told his father that sometimes he could feel people. Not one. Several. As if invisible threads were connected to his chest, and on the other side of those threads, hearts were beating at rhythms different from his own.
His father cut off a piece of meat, chewed slowly, and said that too much imagination got in the way of his studies.
William never brought it up again.
But the threads didn't stop. They grew thicker. Warmer. At thirteen, he started dreaming.
In the first dream, there was snow. So much snow. And a boy with hair far too light to be French, running barefoot down a street William didn't recognize. The boy was laughing. William felt the cold in his own feet, the air slicing into his lungs, and at the same time an absurd, wild joy that wasn't his.
He woke with his heart pounding and his feet freezing beneath the blanket.
In the second dream, a few days later, there were cherry trees. Pink petals fell over a dark-haired girl reading on a wooden bench. She lifted her eyes from the book and looked straight at him—as if she knew he was there, watching. William felt his face grow hot.
Then came others. A boy on a beach of white stones, the sea so blue it hurt to look at. A voice singing in a language he didn't know, but that made his chest ache with longing. Hands working dark soil, carefully planting something.
William began writing down the dreams in a black notebook he hid beneath his mattress. He told no one. But every morning when he woke up, the first thing he did was close his eyes and search for the threads.
They were there. They were always there.
Jack discovered at nine that he could feel the sun in a way no one else seemed to.
Not the heat. Not the light. Something inside the sun. As if the entire star were a beating heart, and he could hear every beat if he stayed quiet enough.
He was lying in the backyard of the house in Austin, Texas, his arms spread wide on the grass, when it happened for the first time. The world fell silent—the crickets, the wind, the distant sound of the television in the living room—and in place of all of it came a presence. Not one. Several. As if the sun were showing him that there were other people in the world who also knew how to listen.
Jack opened his eyes and stared at the sky until tears streamed down his face. Not from sadness. From something he had no words to describe.
His mother appeared at the back door and asked if he was okay.
“I'm fine, Mom,” he said, wiping his face with his T-shirt. “The sun is beautiful today.”
She laughed and went back inside.
Jack stayed there for another hour.
By fifteen, the dreams were already part of his routine. They came almost every night, mixed together and confusing, as if he were changing channels on a television that only showed other people's lives.
There was one that always came back: an enormous, noisy city full of glass buildings and lights. And in the middle of it all, a boy with brown skin and dark eyes, sitting in a high window and looking at the city as if it were too small for him. The boy had a book in his lap, but he wasn't reading. He was thinking. Jack felt his thoughts like an electric current—fast, sharp, restless.
Every time that dream came, Jack woke with an overwhelming urge to go somewhere. He didn't know where. He only knew he had to go.
At sixteen, during football practice, Jack took a hit to the shoulder and fell to the ground. For one second, before opening his eyes, he felt seven different beats in his chest. Seven rhythms. Seven breaths that weren't his.
The coach asked if he had hit his head.
Jack said no.
But he spent the rest of practice with his hand on his chest, counting.
Ferdinando had always known the moon was his.
Not in a possessive way. In an inevitable way, like knowing his own name. Since he was nine, when his grandmother took him out onto the porch of their house in Crete on nights when there was no moon and he stared at the dark sky, searching for what wasn't there.
“There isn't a moon tonight, Nando,” his grandmother would say with a laugh.
“There is,” he would reply seriously. “You just can't see it.”
He could feel it. The moon was there, hidden, and he knew exactly where. As if part of him were in the sky alongside it, invisible but present.
At nine, the first sensation came during one of those nights. Ferdinando was sitting cross-legged on the porch floor, his eyes closed, when he felt something that wasn't the wind. It was as if someone had sighed inside his chest. A sigh that wasn't his, coming from far away, very far away, carrying a sweet weariness, like that of someone who had just laughed too much.
He opened his eyes and looked at his grandmother.
“Grandma, did you sigh?”
“No, sweetheart.”
Ferdinando looked up at the dark sky and smiled.
By sixteen, the dreams already had faces.
Not clear faces—they were like reflections in disturbed water, always trembling, always almost there. But he recognized the sensations. There was someone who smelled like old books and strong coffee. Someone who carried the scent of wet grass and sweat. Someone with cold hands and a warm laugh. And someone—this one was the strongest—who thought so quickly that Ferdinando woke with a headache, as if he had tried to keep up with a race that wasn't his.
Ferdinando now lived in Athens, attended a school near the port, and every night before bed he did the same thing: closed his eyes, took a deep breath, and searched for the others.
He didn't know who they were. He didn't know where they were. But he knew they were searching too.
Calisto wasn't looking for anyone. No one needed to look for him.
He simply knew.
At nine, the first time he felt it, he was helping his mother close the fabric store in Florence. It was late afternoon, and the orange light poured through the display windows, making the silk pieces shimmer as if they were alive. Calisto was folding a cut of dark blue velvet when his hands stopped.
It wasn't a decision. His hands simply stopped, and in place of the fabric's touch, he felt something else. Skin. Not his. The skin of someone who was far away, very far away, and who at that exact moment had also stopped whatever they were doing.
Calisto looked at his own hands. They were trembling.
“Mom,” he called, his voice low. “There's someone...”
“Someone where, honey?”
He didn't know how to answer. Because the person wasn't anywhere he could point to. They were inside him. Inside and far away at the same time.
By seventeen, Calisto had made peace with the fact that his mind wasn't his alone.
The dreams came in layers. Sometimes he dreamed of a place and knew he was seeing through someone else's eyes. Sometimes he dreamed of a pure emotion—anger, or tenderness, or a loneliness so vast that he woke with tears in his eyes without knowing why.
There was one dream that repeated more than the others. In it, Calisto was in a city he had never visited. The buildings were tall, the traffic was chaotic, and the air smelled different—hot, humid, mixed with something sweet he couldn't identify. And in the middle of that city, in an apartment high up in a building, someone was awake late at night, a desk lamp illuminating page after page of notes.
Calisto never saw that person's face. But he felt their mind as if it were music—fast, precise, full of notes connecting into patterns he could almost understand.
Every time he woke from that dream, Calisto lay still in bed for long minutes, with the feeling that he had just lost someone he hadn't found yet.
One Sunday afternoon, while walking alone through the streets of Florence, he passed a window reflecting the sunset. He stopped. In the reflection, for an instant, he could have sworn he saw another face besides his own.
He blinked. There was only him.
But his heart was beating as if there were two—or more—of him.
