I actually checked myself into the hospital because of this. Well, that and I needed to get out of that house and where someone would actually listen to me.

It was a lot more common when I was younger - I seem to have mostly outgrown it, having intrusive flashes and images of myself being brutally attacked or mutilated or otherwise harmed. I seem to have gotten past that, numbed myself to my usual triggers.

It's still quite easy to imagine myself in the place of someone being harmed, though.
