To see a hallway in your dream, symbolizes self exploration and the beginning of a path that you are taking in life. You are going through a transitional phase in your life and journeying into the unknown. It signals spiritual enlightenment, emotional growth physical prowess, new opportunities and mental passages in your life.
There is not much significance to a hallway other then denoting an abnormal period of worry and concern, so this dream should be interpreted using the other symbols in the dream and reserving hallways under, *worries*.
