To dream of a plague raging, denotes disappointing returns in business, and your wife or lover will lead you a wretched existence.
If you are afflicted with the plague, you will keep your business out of embarrassment with the greatest maneuvering.
If you are trying to escape it, some trouble, which looks impenetrable, is pursuing you.
This dream signifies some mental disturbance, probably arising from an infection or other medical problem.
See your doctor.
