Thanks for the input, both from those who have found this technique helpful and from those who empathize with how very weird it seems to me.

I think I will share with my T my initial reaction of ewwwwww, and we'll see how it goes from there. I have used imagery in a limited way to get rid of the worst of the suicidal thoughts, so it may be something that's helpful, but I don't know. I still am having a very strong reaction that NOBODY goes in the room with the kid.
