if you were in my location and this was me and my treatment provider no feeling like my neck was attached to strings and being moved by a puppet master would not be dissociative symptom. it would be a symptom of my having psychosis or medication problem. simply because of the diagnostics my location goes by that reality testing remains intact with dissociation. since there really isnt strings attached to my neck and there inst really a puppet master pulling those strings it is not focused in reality, out of touch with reality (which is what psychosis is here in my location)

my suggestion is use some reality testing when this happens. touch your neck is there really strings attached. look behind you is there a puppet master pulling the strings. look in a mirror are your muscles actually coming through? if the answer is no these things are not really happening then theres your answer...its not associated with dissociative disorders.

next question if not dissociative what can it be...

all kinds of mental and physical health problems and normal things too can cause this to happen...

going on the assumption that you have not lost touch with reality (knocking out the problem of psychosis) and are using your description as a metaphor ...

stress can make muscles feel tight, hard to manipulate, so can medications so can lack of sleep, so can ....see what I mean it can be just about anything.

with me muscles tight, spasms, pain, ...is Multiple Sclerosis. A physical health problem.

with my DID and the few alters I did have co consciousness with again no it didnt feel painful, stiff uncontrolable muscles trying to come through my neck nor the feeling of strings at my neck and a puppet master.

it felt normal. my DID happened to me in very young childhood before I was even school age. which means i grew up my whole life with alters taking control any time I encountered a problem that i could not handle in other words every time I got triggered into dissociating. that means this was my normal. it wasnt painful triggering upsetting, felt strange or what ever. it felt normal. my physical body continued to function just like normal. if anything it functioned better because what I could not handle \do the alters handled\did for me. when I was co conscious i was numb, spaced out foggy minded like looking through a glass window... what was happening on the other side of the window wasnt affecting me, I was safe and sound and numb far away from what ever was causing me to dissociate (switch into that alter) if anything I was calm and relaxed. I would be able to see still but it was like it wasnt me, reality testing still remained intact, i could tell my therapist or who ever was near me was talking to Rainy and that it was Rainys voice not mine talking. Rainy may have been crying and upset but I was not I was safe, calm numb relaxed.

this is how it was for me, for others it may have been different... my suggestion is if this continues to bother you contact your treatment provider, they will be able to evaluate whether this is dissociation in you or if its any number of other normal, mental or medical problems and if its dissociation related they can teach you grounding and other tools so that this no longer happens to you.
