Rioting
To dream of rioting represents feelings of being restless with something you disagree with. Anger, resentment, and strong with for change. Pressuring others to change. Feeling upset about an issue. Feelings about multiple aspects of your personality that are confronting a stubborn problem. Feelings about not being willing to put up with a problem ever again. A need to be louder about problems or frustrations than usual.
Negatively, rioting in a dream may reflect feelings of being too little to confront a big problem. Internal frustrations that want to be louder or more assertive about problems, but aren't initiating it. Jealousy or desire to confront frustrations.
Alternatively, rioting in a dream may reflect your feelings about other people being upset with decisions you've made. Confronting a lot of resistance to your personal style of handling a situation or to you power to control.
Example: A man dreamed of seeing Greek people rioting against the fence of a Greek Presidential building. In waking life he was starting to resent supporting his father and starting to become more assertive in pressuring him to change his ways.
