When interpreting this dream, try to remember your feelings upon awakening. Going up and down the stairs could mean several different things. It could represent changes in consciousness, movement from one inner plane to another, or a change in understanding. In a more material sense, it could represent a rise or fall in economic or social status and the general efforts that are required to accomplish life’s small and large goals. Climbing may represent an achievement of your ambitions and a movement in a positive direction. Descending may symbolize your doubts or a period following hard work and achievement of a significant goal. Generally, dreaming of ascending a stairway connotes movement in a positive direction while descending is indicative of a down period or negative flow of ideas or actions.
