Triggers, ladies, triggers!! I know this is a tough one to get.. but there is a difference here. (if I hadn't gone to school for this.. I would be reacting the same way...)
There is a difference between just screaming and hysterical screaming. A very big one. PTSD screaming (LOL, now which of us hasn't done this???) will calm down after a bit, without being slapped or grabbed etc.. Hysterical screaming does not. It doesn't stop until you pass out or something happens to make you quit. I know that just reading the first post, you probably don't see the difference, but I did right off the bat. Slapping someone who goes into hysterical screaming is a first instinct and is not violence. It's just like our programming for survival, same type of instincts. He had to do something and without the prevous knowledge of the 'hug' or otherwise, there was no choices there. Now he has choices. This was a first and only step, now comes the harder stuff! Anyways, back to my point. Hysterical screaming is a different experience (yep, I've been there.. very nasty.) When I went there, I was aware that I was screaming and it was blood curdiling, but I could not stop. It was like watching myself. When this starts, the person is beyond any sense of control, sense of self, anything. It's like the shell is reacting while the mind left. You have to get the mind back. So, I realize this seems violent to everyone, but it's not. I do not suggest it becomes the common method to deal with it but for the first or second time, there is nothing wrong with it. It's not going to damage the person, it's helping them temporailly by shocking them.
Hey, which reminds me, JIM, try throwing cold water and the like on here also if this happens again. That could also work.
