To dream you are abusing someone represents your hostility to a person or situation. It may also reflect a lack of appreciation or respect for other people or some area of your life. Abuse may point to self-defeating thinking patterns such as regret, guilt, or feeling depressed.
To dream of being abused represents issues that you perceive to be hostile to your well-being. A reaction from a person or situation in real life that you feel is too harsh or overcompensated.
If you were abused in real life then the dream may be a sign that you need to begin to confront your past by speaking to someone.
