To see construction in your dream signifies a new surge of energy, growth, ambition and renewed confidence. It may also represent the rebuilding of your own life.
To dream that a building is under construction suggests that you need to work on some aspect of yourself and better your mind or body.
To dream that you are walking barefoot on a construction site means that you are not ready to put in the work necessary to improve your mind or body. Perhaps you are in denial that you need any improvement.
