Usually I can control the reactions, and things that my DCs say. However, in this dream, I had a rebellious DC.

I was on a nice crescent somewhere, and there were houses on both sides of the street. There was this adult woman coming at me with a tiny knife (probably the half the length of your thumb), but it creeped me out. I told her to 'stop' and held out my hand, but she said, 'who cares' and started running at me. I summoned a bubble around myself to protect myself, but she went through it like it was air, and stabbed me right in the arm. I could see blood and I freaked. I woke up, but it turns out it was an FA. I caught it by doing the digital clock RC, and the time changed from 8:27 to 8:28 and back again. But I still remembered the dream. It bothered me.

Suggestions? Tricks on how to stop this?
