You have low self-esteem and lack confidence in yourself. Or you may be dealing with issues concerning your self-identity. You are unprepared for what is ahead for you.
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.
