To dream of your knees represents a form of assistance and guidance that will be bestowed on you. It also refers to any emotional feeling you may have, as well as feelings of incompetence and issues of influence and control. It further suggests you may be overwhelmed with your daily responsibilities and obligations.
To kneel in a dream is to accept that you are not in control of a situation. You may feel that someone else has a strong power over you or you may be seeking guidance in overcoming a difficult problem.
