I've been thinking a lot along these lines for a while now. I have researched DID and MPD since I got to know someone who had MPD. I came to
understand that it was as if I had a very slight case of DID, and began to notice the signs of it in other people.
One could make a case that online internet personas are as if a form of DID. One could also make the case that our mask we wear in society is yet
another persona.
I feel that most people are fractured quite a bit. They have a self they show to their close friends, a self they show to the general public, a self
to show for business situations, and a self that they rarely get to know...the source, subconscious, higher self..etc...
It seems that most people are every so slightly aware that things are very off. These are what you would refer to as the SJ's from an Myers-Briggs
Jungian take (google: MBTI) . They make up about 45% of the population, and have an innate neural structure so as to defend the social contract and
status quo by any means necessary. The other part of the bulk is the SP's, and they are able to think a little on the "what if" side of things, but
still feel it best not to buck the system.
Then you come to the NJ's and NP's. The NJ's are tasked with imagining the future, and manipulating people into their vision of the way things must
be done. NP's are a little more unsure about their vision, as new possibilities are constantly reshaping the image, and are also more laid back about
how to implement their vision, or even if it should be in the first place.
So who is most likely to have PTSD
It's the NF's. The idealists the ones who dream up a best case scenario, and feel that their vision can,
and should be implemented, and nothing else will suffice. They will feel incomplete, and even unreal when they are asked to perform in ways that are
not in tune with their vision and ideals. The more friction between the social norms, and their vision, the more unreal they become. Eventually they
fracture into many pieces.
I think that you are likely an Idealist, OP. I think you project your ideals onto the average individual, and feel that they must be as broken as you,
but they just aren't aware of it, and must be suffering from some sort of PTSD as you may be.
PTSD is pretty hardcore, though. I don't think most people are suffering from it, rather they are being pressured to have microfractures in their
psyche.
