Flashbacks are just that way. I think you did well. A good trigger phrase she might be trying to incorporate (you can ask her) is "It isn't happening now..." whatever she's being triggered to remember... the worst thing I experience when an alarm goes off is that no one bothers with it, or responds and I NEED to!!!! When I'm unable to get out of the area, I become paralyzed inside with fear. Sure wish I had someone with me to lead me out and be with me when those things happen.

Many good suggestions already given. TC!
