Great caution is called for. You are getting caught up in guilt.
If you uttered a curse against someone in your dream, you are in danger of losing the respect of friends. Curb your temper and impulsive actions. However, if the curses were directed at you by somebody else, a rise in social status through new and influential friends may be expected.
To dream of hearing Curses and rough language presages a visit of ceremony.
If you dream of cursing at someone, then you are venting out your anger, frustration and displeasure.
If someone is cursing at you, then you are venting out feelings of being attacked and criticized.
A dream of being cursed is a venting dream that is helping you to release any projected negativity and guilt you may have taken on. See Venting Dreams and Karma.
