The meaning of a dream about briefcase.
The meaning depends on details of colour, condition, etc., but as a general guide: a well-worn case predicts business success; a new briefcase is a warning against making changes or decisions without adequate investigation; a full briefcase is telling you to pay more attention to your personal affairs, and an empty one predicts success with your current plans.
To lose your briefcase is a dream of contrary and forecasts an unexpected profit, but to find one suggests that you must watch your step very carefully indeed to avoid a business disappointment.
