Here’s one perspective:
The aggressive forces in your dreams represent the parts of yourself that you typically restrain and subdue. You do so possibly because you are threatened by the potential chaos or damage that they could cause, whether within your mind and life or to people around you. That’s why they are showing up as dangerous, violent, or malevolent forces.
As you face them squarely and head on, your relationship to them will change. They will begin to work for you rather than being perceived as threats.
As far as practical points to help facilitate the process, bodywork and expressive work. Engage in activities that engage your physical energy and willpower. Could be as simple as ping-pong or basketball. Or could be running, hiking, or simple workouts. (Whatever body-based activities you do will give you a chance to see the positive, constructive sides of those same forces within you.). Expressive activities (writing, singing, or even to some extent meditating will allow you to facilitate the processing and reorganizing of your perceptions and feelings).
Not the only way to look at this, but it’s one view.
