It was horrible and quite similar to what I myself experience as hypnagogic horror hallucinations form time to time. But it seems to be a constant cycle of horror in which this part is captured and feels very real to them. I still can repeat this touch and it is the same stuff they feel and see again.
Because of this similarity to my own hallucinations I started to wonder if they actually are stuck in an endless cycle of hallucination (is it possible that one part of your brain is constantly hallucinating?) of if this is more of an inner-world thing going on. Since we were encouraged as kids, that the stuff which appeared in these hallucinations (like demons etc.) are real. It could be actually a source of trauma if a kid experienced such hallucinations.
Do you think that hallucinations could cause trauma? Or that rather some trauma could cause hallucination?
It also made me think of a lot of other weird perceptions I have on a daily base and realized that actually many of them also would maybe qualify as hallucinations (persons or body parts I "see" around me, but which are not there or don't look actually like how I see them sometimes), because I am not able to control them, even if I am aware that they are not "real".
But they also could be projection of other parts (which I did think for a while now). Or are this projections also sort of hallucination?

Okay, that now was a lot of confusing babbling (because, again, I feel confused

What I actually wonder is if others here, who experience multiplicity, also experience stuff that could described as hallucinations and if you would describe most of this as inner-world things going on and bleeding over to your outer-world perceptions.
Common things I experience myself (I don't do drugs btw. One of the reason is, that I already feel like being on drugs quite often).
I usually know that what I experience is not physically real, but I can not control it compared to other vivid imagination stuff, which I can shut down if I don't like it.
*** TW: includes some body horror descriptions:
- Hearing screams or voices (mostly inside)
- Hearing and even feeling my cat, while she actually sleeps silently somewhere else (outside)
- Hearing knocking on door or ringing of bell/phone (outside)
- Seeing other arms which are attached to my body, but act on their own. The usually try to assault me
- Feeling like my own arms are moving out of the physical body
- Feeling someone standing very close behind me (can be threatening or protecting)
- Seeing/feeling other cloth on me than I actually wear, or seeing a completely different body
- Seeing my body being ripped open or treated in other horrific ways for a moment, but without feeling pain.
- Feeling sudden pain but without actual physical source or other visual connections
- Seeing other faces in the mirror than my own (usually very short).
Plus hypnagogic hallucinations, which are the most intense and real ones and usually include being sexually assaulted by demons. This seems to be a rather common topic in this kind of hallucinations.
On the other hand there is a part who seems to experience this all the time and not only while going to sleep and also not being able to identify it as "not real".
*** End TW
Didn't mention our synesthesia, which also has some hallucinogen qualities, but is so abstract that it probably is not related to inner world stuff or other parts.
Not sure if someone did read through this quite poorly structured post. But I'd still be interested in other's experiences with hallucinations-related stuff and DID even if you don't want to go in to the rest I did write.
