To dream of a riot indicates that you are feeling as though things in your life, and possibly in the world as a whole, are completely out of control.
Particularly if this is a recurring dream, it is important for you to look at what it is in your life which is under your control, (even if it is only seemingly small things, such as your attitude, or what you eat or wear) and that you pay attention to controlling those things.
Whether you are participating in anarchy or simply joining in on what others are doing consider ways in which your own actions are detrimental in your waking life and take time to think about what you are doing with your life.
Any steps that you can take to help yourself feel more “in control” of yourself and your fears, is likely to be a good thing now, however of course you cannot control other people.
Consider whether or not there was anyone at the dreamed riot that you know. If there are recognizable people there, you may have some underlying conflict with those people and/or be worried about how they will “get by,” in coming days.
This behavior in a dream is concerning because in your waking world, it shows you are on a very bad path but likely aren’t consciously aware of the danger you are putting yourself into. Rioting in a dream is akin to acting out and reacting rather than being level headed and responsible. These kinds of actions can end up getting you in trouble or causing long term detriment to your life.
Riots can even sound like fun when one is upset with the government, a social injustice, or when freedoms are revoked. Remember that the people hurt in a riot are usually local business owners, citizens, and people just like you. Rioting creates social destruction and at the root breaks down the will of the people that are then left to deal with broken buildings, rubble, and sometimes tainted water or food supplies.
Sometimes others need attention more than you do and it is a sign that you need to help those people or a specific person around you find the inner voice and strength to express themselves creatively and healthily. You can speak up for people right now as you likely have some skill or experience to help others.
Do not allow yourself to feel out of control as you have the power to take control over the situation once the activity and reactive behavior dies down.
Sometimes quelling a riot and can indicate the calm before the storm in your waking life.
