Dreaming of being hungry can symbolize a lack of fulfillment. It is common to be doing something work related in a dream - only to be focused on the food or eating when it doesn't seem appropriate. That is because your dream is connecting the idea of fulfillment to your need for recognition at work, or the need to find the more fulfilling work. Food related to riding in a car would be tying the idea of fulfillment to your drive. The ancient Chinese have a great saying: "nourish what is for the belly and not the eye." See also Food.
