Lucid Dream Justice

Already somewhat lucid, I observed a security guard causing significant havoc by pepper spraying people for minor infractions. I disarmed him, taking his pepper spray, and began to spray him as he had sprayed others. I told him that he had abused his small amount of authority, explaining that true authority isn't about abuse or strict enforcement, but about using one's position to help those under their care. Suddenly, a serial killer-like figure appeared, murdering someone directly in front of us. The security guard, overcome with fear, stood up and fled. I then resolved to intervene. We fought, but he proved unable to harm me. My recognition that this was a dream allowed me to wield powers he could not, ultimately leading to his defeat.
