Almost all of my dreams every time I woke up I can still remember but haven't dreamed in the bus.. well, my interpretation would be ... life is a journey that we are heading somewhere of our choice and of our decisions. The bus represent our long term goal to travel our life, it is not how long it would be, it is how much we enjoyed the journey till we reached the destination. The bus represent the comfort in your travel, it might also represent your certainty taking the right direction in your life.
