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.
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 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.
