Roen kept a notebook by his bed that was not a journal. He had started it eleven years ago, in the first weeks after his transfer to the Infrastructure Analysis Division, not to record his dreams but to catch the problem-solving his mind did between sleep and waking: partial solutions, half-formed patterns, the kind of associative work that dissolved if he didn't write it down before standing up. The notebook had grown to four volumes.
The maintenance schedule for the district water filtration systems had been updated in March: the cycling interval changed from fourteen days to nineteen. The memo had come from central planning without explanation. Roen had filed a query. The query had been received and not answered.
Two weeks before the memo arrived, he had recorded a dream in which he stood in a room of water tanks, connected to each other by pipes, and understood in the way you understand things in dreams, without needing reasons, that the visible cycling interval was not the real interval, that something underneath was running on a different clock.
He had written it down and thought nothing of it until the memo.
He went back through his notebooks then. He was looking for something he could not name. He found two other entries with a similar quality: a dream about traffic signal timing that preceded by eleven days a modification to the city's adaptive routing protocol; a dream about an underground cable network that came nine days before a documented update to the fiber routing infrastructure in his district.
Three events. Three was not a number from which conclusions could be drawn.
He noted the correlation anyway, in a separate sheet he kept at the back of the current notebook. Date of dream, date of infrastructure change, domain, interval.
He had been tracking it for four months when the pattern stabilized. Not three events. Seventeen. Average interval: twelve days. No misses. Every infrastructure modification in his division had been preceded by a dream about the infrastructure that would be modified.
He sat with this for a long time. There was no mechanism he could identify. The infrastructure decisions were made by central planning, in processes he had no access to. His dreams were his dreams. There was no connection he could see.
He began writing his dreams down with more care.
