Sleep Report
A sleep-tracking app starts to report a second sleeper in a bedroom that holds only one.

I bought the app because Sol said I snored, and I didn't believe them. Sol had moved into the spare room a month earlier. The spare room had an old futon and a box of Sol's things that Sol said they'd unpack later. I didn't ask why. I only wanted the app to settle the snoring question.
It recorded sound through the night and played back a loudness graph in the morning. There was a feature called Sleep Story that summarized the night in a few sentences. It liked the word *restful*.
For a week the summaries were dull. I was a light sleeper. I shifted position twice a night. No events.
On the Tuesday of week 41, the summary changed.

**Sleep Story — Night of Tuesday**
*You had a restful night, with some light stirring between 02:10 and 02:40. A brief period of paired breathing was detected at 03:17.*
- **02:14** — Breathing slows to a steady rhythm.
- **03:17** — Two breathing patterns. Duration: 2 min 41 sec.
- **03:20** — One breathing pattern.

The pop-up explained *paired breathing*: *When two people sleep in the same room, their breathing sometimes syncs. This is normal and often a sign of a healthy relationship.*
I was alone. Sol was in the spare room, one floor down, on the other side of the house.
I played the recording from 03:17 through the phone's speaker, lying in bed with the lamp off.
The first forty seconds were ordinary. The fridge through the wall. The street, far off. My own breathing, slow and even.
Then, under my breath, a second breath began. Close. It matched mine for about a minute with a precision I found hard to listen to. Then it fell slightly behind, the way a person does when they're listening to someone and copying them on purpose.
It wasn't Sol. Sol breathes through the nose with a faint whistle on the in-breath. This was quieter, slower, and it stopped every few seconds, as if the person wanted to hear whether I had noticed.
At 03:19 the second breath moved closer to the microphone. You could hear the change in the room, the way sound thickens when a mouth comes near a phone.
At 03:20 my own breathing stopped. For two seconds there was nothing on the recording, not even the fridge. Then my breath came back, and the second breath was gone, and the recording continued as if nothing had happened.
Except that the recording had a new last line. It was not a sound. It was a timestamp, and it was the current time.

I told Sol in the kitchen the next morning. I played them the clip while they filled the kettle.
Sol listened twice without speaking, the way you listen to a voicemail from a number you don't recognize.
"That isn't me," they said.
"I know."
"I've been hearing it too," Sol said. "Through the wall. Every night about three, someone breathes in time with me. Slow. Then stops, just before I do." They put the kettle down. "I thought you'd come downstairs and sat outside my door. I thought that was why you bought the app."
"I bought it for the snoring."
"You don't snore," Sol said. "You never did."
On the counter between us, the kettle began to tick as it cooled, and in the quiet I heard, from the stairwell, a bare footfall on the fourth step, then a pause, then a second footfall in the same place, half a beat behind mine, as though whoever was on the stairs had been trying to match my weight before putting theirs down.

I tried to uninstall the app. It asked whether I wanted to keep my data. I said no. It asked again, more gently, whether I wanted to share a final summary with a caregiver. I said no to that too, and the screen went dark, and I lay down on the bed without thinking about it.
I woke to light through the blinds at 07:40. I felt rested, more than I had in years. The app icon was back on the home screen. I hadn't reinstalled it.
Above it, a banner: *Your Sleep Story is ready.*
I didn't open it. I lay still and listened.
Downstairs, Sol was moving around the kitchen. The tap ran. Through the floor came the faint whistle of someone breathing in through the nose, and under it, a second breath, slower, very close to the first, copying its rhythm so exactly that I could no longer tell which was in the room and which was in the house.
I stopped breathing. The second breath went on for a while, patient, as if it had all the time in the world. Then it stopped too, one beat after I did.
I have not slept properly since. I lie awake with the phone face down on the nightstand, and every few minutes it lights up, and I know without reading it what it says.
