To dream about a hallway represents the initial steps of a new journey. You will uncover your unknown true desires. This indicates a spiritual quest, but can also take on physical and emotional aspects as well. This is usually a sign of a changing aspect of 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’.
