Also the term "dissociative fugue" is one on which the client loses their sense of personal identity and goes out and does things that they cannot remember - as the actions were undertaken by another part of themselves of which they are not conscious.
This is exactly what people with DID/MPD claim happens to them and it is frequently used as a way of avoiding responsibility for doing bad things, or not preventing bad things, in my expensive personal experience.
I have personal experience of something similar, as do many traumatised people. Something bad is happening that needs attention and yet one feels paralysed. There is awareness of something bad and yet is is so distressing that one compartmentalises it. This is not the same as dissociative fugue but has dissociative elements.
The various controversial organisations claiming to specialise in dissociative disorders continually create new categories of dissociative disorders and break the varying elements of the different disorders down and run expensive training courses about them. It is a gift that keeps on giving to the people running the training courses. Ker-ching ker-ching the money tap keeps on flowing
They may claim that a "dissociative fugue" is seperate to what happens to people with DID/MPD but the basic mechanics are identical.
A person does something, very often something bad, negligent or even criminal, and then claims to have absolutely no memory of the event.
They may embark on a quest, with the aid of their therapist, to "recover the memories".
In my experience they recover memories of incest of SRA that they claim removes or diminishes their repsonsibility for their bad actions or neglect. In fact they may even get competititve with those they have harmed, I have seen this. "You're angry at me for doing x horrific thing, but I was forced to sacrfice babies by a satanic sect so my trauma trumps yours". I have witnessed this insane crap with my own eyes.
In fact over the last few years the "brand" of DID/MPD has changed. Back in the videos of the 80s and 90s you will see extremely disturbed women crying, screaming and acting like traumatised young children.
Nowadays you will see many people claiming to have DID earning significant remuneration, obtaining gifts and receiving narcisistically gratifying social interaction from millions of people. The similarities between the videos of these influencers and the non-binary / trans young people influencers are obvious to anyone who is paying attention.
These latest manifestations of people with DID claim to have some memory of their "alters", so it may be that as the chamelion that is MPD/DID/complex trauma evolves over time, dissociative fugue can become categorised more clearly in such a way that lucrative training courses can be delivered to the benefit of all the quacks on the disociative disorder gravy train.
Having said that, I think it is highly likely that within these networks of quacks, charlatans and mountebanks, there exist many well meaning pracitioners who have simply fallen in with the cult like dynamics prevalent in these organisations and are genuinely trying to help people and are simply misguided.
Part of the problem is that dissociation is a real thing. The mind / body connection is a real and fascinating thing. Somatic disorders are real.
There is an urgent need for this important area of study to be liberated from the confines of the cultic milleu that currently controls it.
