Dreams dictionary: Plague

Dreams dictionary: Interpretation 1
To dream of a plague indicates that you are being confronted with a broad issue that affects those around you. The decisions that you make will have a major impact and large-scale consequences.
Dreams dictionary: Miller Dream Interpretation
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.
