The foundation you have built reflects in your dreams, showing your current state of the mind and how safe you feel being on that floor. If the floor is made of wood, looks nice and shiny, then such dream shows the strong basics you have made for your life. You have the targets and getting them on the right way. If the floor has minor defects, is rotten or broken, then you should start reconsidering the priorities in your waking life. Perhaps the dream suggests you to start being more serious when building your own life.
