I am Dr. Robert Hayes. I am forty-two years old. I am a psychiatrist at the Harrington Research Centre in Boston. I have been for eighteen years. I specialise in dissociative disorders. I have published thirty-seven papers. I have received two awards. I am, by every measurable standard, successful.

I also cross between worlds.

I do not mean this metaphorically. I mean it literally. I close my eyes in my office, and when I open them, I am somewhere else. Not a different room. A different world. A different life.

The first time it happened, I was sitting at my desk, reviewing a patient's file, and I felt a pressure behind my eyes, like the pressure you feel when an airplane descends, and then I was standing in a room that was not my office, wearing clothes that were not my clothes, and I was holding a gun.

I am not a violent man. I have never fired a gun in my life. But in that room, with the gun in my hand, I knew exactly how to hold it, how to aim it, how to pull the trigger. The man on the other side of the room deserved it. I knew this the way I know that the sky is blue. I pulled the trigger. The man fell. I felt nothing.

When I opened my eyes, I was back at my desk. The patient's file was still open. The pen was still in my hand. Three seconds had passed.

I wrote it down. In a notebook I keep specifically for these events, I wrote: Day 1. 2:47 PM. Office. Gun. Man fell. Felt nothing.

The second time, I was a father. A man named Victor, with a wife named Elena and a daughter named Sofia. I was holding Sofia—she was maybe three years old, with dark hair and dark eyes and a laugh that filled a kitchen with light—and I felt a love so vast and terrifying that it made my chest ache. I held her and I knew, with a certainty that no patient file and no scientific paper had ever given me, what it meant to be someone's entire world.

When I opened my eyes, I was back at my desk. The pen was still in my hand. Three seconds had passed.

I wrote it down: Day 3. 10:15 AM. Office. Father. Sofia. Felt everything.

The crossings became more frequent. More vivid. More real than the office, the patient files, the coffee that sat cold on my desk because I forgot to drink it.

I became Thomas, a prisoner in a cell so small I could touch both walls with my outstretched arms. I felt the weight of years—seven of them, I counted—pressing down on me like a physical force. I felt the slow erosion of hope, the way it doesn't disappear all at once but wears away, grain by grain, until all that's left is a flat grey surface that looks like acceptance but is actually something worse.

I became the scientist, Dr. Moreau, working in a laboratory that smelled of antiseptic and something else, something organic and wrong. I was modifying genes. I was trying to create something new, something better, something that could survive in a world that was breaking. I felt the thrill of discovery, the intoxicating rush of standing at the edge of the known and reaching into the unknown. And beneath the thrill, something darker. A hunger. A need to create that was almost indistinguishable from a need to destroy.

Each crossing gave me something. Each crossing took something away. I was becoming a patchwork man, stitched together from the fragments of other lives, and I was no longer sure which fragments were mine and which belonged to Thomas or Victor or Moreau or any of the others.

Dr. Margaret Sullivan noticed. She is my colleague. My friend. The only person at the centre who knows about the crossings. She is a small woman with sharp eyes and a voice that can be gentle or lethal depending on who she is speaking to and what she has to say.

"Robert," she said, one afternoon, in the break room, looking at me the way a doctor looks at a patient who is trying not to be a doctor. "You're changing."

"I'm evolving," I said. And I meant it, because in my mind, the crossings were not a disease. They were an evolution. I was becoming more than one person. I was becoming everyone.

"You're becoming no one," she said. "There's a difference."

She was right. I knew she was right. But knowing and being are not the same thing, and I had learned this, in one of my crossings, from a man who had spent his life studying the difference.

I became that man. A philosopher, perhaps, or a madman. Maybe both. He was sitting in a garden, watching butterflies, and he told me that the self is not a thing. It is a process. A conversation. A argument that never ends. And when you add too many voices to the conversation, the argument stops making sense. When you add too many people to the self, the self stops being a self.

"I know what I am," I told him.

"Do you?" he asked. And he smiled, and the smile was not unkind, and it was the last thing I remembered before I opened my eyes and was back in my office and the pen was in my hand and three seconds had passed.

I started keeping better records. More detailed. I noticed patterns. The crossings were not random. They followed a sequence. A logic. A structure that was almost mathematical in its precision. I was not crossing between worlds. I was crossing between states. States of mind. States of being. States that lived inside me, waiting to be released.

And then Margaret found the records.

She came to my office on a Tuesday, holding a folder that I did not recognise, and she placed it on my desk and said: "Read it."

I opened the folder. Inside were documents. Medical records. Legal documents. A photograph.

The photograph showed a man sitting in a chair in a room that was not my office. The man looked like me. Not similar. Like me. Same face. Same eyes. Same mouth. But younger. Maybe twenty-five. And his eyes were wrong. They were the eyes of someone who had seen too much and understood too little and was trying very hard not to break.

"That's you," Margaret said.

"No," I said. "That's not me."

"It is," she said. "It's you. Twenty years ago. Before the centre. Before the papers. Before the awards. Before the crossings."

She handed me a document. It was a diagnosis. Dissociative Identity Disorder. Severe. Chronic. Diagnosed twenty years ago, by a man whose name I did not recognise, at a facility whose name I did not recognise.

"I don't understand," I said.

"You're not supposed to," Margaret said. "That's the point. Your mind created a story—a doctor, a research centre, thirty-seven papers, two awards—because the truth was too painful to carry. The truth is that you are not a doctor. You are a patient. You have been a patient for twenty years. The centre is not real. The papers are not real. The awards are not real."

I looked at the photograph. The man in the chair looked back at me with eyes that were full of something I could not name. Fear? Recognition? Relief?

"The crossings," I said. "They're not real either, are they?"

"They're the most real thing about you," Margaret said. "They're not worlds, Robert. They're parts of you. Thomas. Victor. Moreau. All of them. They're you. They've always been you. The question is not whether they're real. The question is whether you can hold them without breaking."

I looked at the photograph again. The man in the chair was crying. I didn't know he was crying until I saw the tears. And then I knew, with a certainty that was neither fear nor recognition nor relief, that I had been crying for twenty years and had not known it.

I closed my eyes.

When I opened them, I was not in my office. I was in a room I had never seen before. A small room. Plain walls. A single window. A chair.

And in the chair, a boy. Maybe ten years old. Sitting with his knees pulled to his chest, his arms wrapped around them, his face buried in his arms.

I walked toward him. He did not look up.

"Who are you?" I asked.

He didn't answer. He just sat there, shaking, holding himself together the way a child holds himself together when the world has shown him that it is not safe and he is not strong enough to keep it from breaking.

I sat down beside him. I put my arm around his shoulders. He leaned into me, just slightly, just enough.

"I'm here," I said. And for the first time in twenty years, I meant it. Not as a doctor. Not as a crossing. Not as any of the other things I had been. As a man. As a boy. As the part of myself that had been waiting, all this time, for someone to come and sit with him in the dark and tell him that he was not alone.

I closed my eyes.

When I opened them, I was in my office. The pen was in my hand. Three seconds had passed.

I picked up the pen. I opened the notebook. I wrote: Day unknown. Time unknown. Room. Boy. I am here.

And then I closed the notebook, stood up, walked to the door, and for the first time in twenty years, I left the office and did not come back.
