Mill
A building where grain is ground into flour — the infrastructure that turns the village's harvest into its daily bread.
A mill in a dream is the dream's image of the infrastructure that turns harvest into daily bread. The mill is not the field and not the bakery; the mill is the building that does the necessary middle conversion, and a village without one cannot eat what it grew. The dream brings the mill when something in your life — a system that translates raw effort into usable result, an institution that no one notices until it stops, a piece of infrastructure your work depends on — is the kept middle that the rest of the supply chain assumes. A mill turning steadily, the flour being bagged, is the dream affirming the kept conversion. A mill stopped, the wheel still, the grain piling in the yard, is the dream noting that the middle step has failed, and the harvest is going to spoil for lack of the building that would have processed it.
