Hi Crypts of the mind. I didn't read this until now. It seems like the views without replies have gone and triggered off old stuff about being alone/unsupported now as well. Just to add to everything.
Personally I think PTSD symptoms can settle down for quite long periods of time and then get triggered up by something again. It kicks my butt a lot. Do you have any idea what might have triggered the dream?

I hope you find a way to calm the emotional flashback kind of stuff.
