All the interactions I've had with voolent DCs have been to send them love or try to reason with them. Just his last night, I was in a zombie apocalypse (it's been a recurring nightmare, but today is the first night I've faced it lucidly) and I found this DC who wasn't really a zombie, but she looked scary. I stood before her and calmly asked her why we were hurting each other and why we couldn't just get along. Her whole complexion changed and her eyes turned into beautiful bright blue eyes. All feelings of frustration and fear hanging in the air disappeared at once. It's worked similarly in other dreams, that's why I always do it like this.
