What Does Dreaming of a Mouse Mean?
Traditional Interpretation
According to Ibn Sirin, the mouse most often points to a sly, corrupt person or a hidden enemy; seeing a mouse in the house can, in some interpretations, signify provision and abundance, but also those who squander that provision. Catching or killing the mouse may point to recognizing the enemy and being rid of them—a blessed victory.
Psychological View
In modern psychology and the Jungian approach, the mouse can often symbolize repressed anxieties, small but accumulating stresses, or the need to confront the shadow archetype—the sides of oneself that are hard to accept. Being afraid of the mouse may indicate that the time has come to face inner fears and uncertainties.
