How do you turn dreams into numbers?

The question might be referring to Carl Jung's paper, "On the Significance of Number-Dreams." The paper does not refer to turning dreams into numbers or assigning numerical values to dream images. Rather it concerns dreams that are themselves about numbers or that contain numbers. For example, a dreamer might recall dreamer the number 121843. Jung discusses the different possible meanings of such numbers, which might be dates, addresses, or some other number that has significance in the dreamer's real life.
