In British mythology, the mouse is usually portrayed as weak and timid, but blessed with compensatory traits of intelligence, compassion, and resourcefulness. Dreaming of a mouse, therefore, portends a situation in which the dreamer will be able to turn a weakness into a strength, a disadvantage into an advantage – and thus escape any negative consequences.
Being frightened by a mouse signifies social embarrassment coming up, and if the dreamer wants to avoid it, he or she can look to other symbols in the dream.
Mice scurrying around freely, wreaking havoc in their surroundings, indicate family squabbles ahead.
Seeing a mouse being chased by a cat is a warning not to let others interfere in your affairs.
