Insanity – Dreaming about insanity is a sign that you are not in control of your thoughts or emotions. In waking life, you may feel that your thoughts and reactions are completely logical, but your dream about being insane is telling you that this is not the case. If you dream of doing things that frighten you or that you think you would never do in your waking life because of your insanity, this indicates a fear of being out of control of yourself. Some emotion is being harbored deep inside you, and it is very strong and possibly very dark. It is best to bring it to light and come to terms with it now, rather than letting it continue to build until you are truly out of control of your own actions in your waking life.
