Milking cow
A cow in regular yield — a steady producer of plain supply taken twice a day.
A milking cow in a dream is the dream's image of a steady producer of plain supply, taken from twice a day and required to keep going. The cow's labour is not dramatic; it is constant. The dream brings the milking cow when something in your life — a job, a creative output, a parental role — is currently being drawn from at a regular interval, and the question of whether it is being fed enough in return is alive. A milking cow in good condition is the dream affirming the sustainable rhythm. A milking cow underfed and still being milked is the dream noting that the extraction has continued and the input has not kept up, and the yield is going to drop.
