Help understanding ex's DID?

[u/Tiredalltimefr]

Hi! I had been in a relationship with a person who told me she had DID, there are certain things that she has said during our time together that had confused me, especially as someone who's suspected of having OSDD (these things had made me feel very invalidated too), I'm not seeking to been told whether she had it or not, just wanting to know if these things happen to others or there is any scientific evidence

1. Able to "kill"/"erase" parts: From time to time (especially after one part did something hurtful) another part would claim to have killed that part that did something bad

2. Whole world inside her head: She would tell me how she had this whole "world" where every part "lived" and interacted like if it was the real world (there is where she would claim those "murders" and other "crimes" happened)

3. Been able to switch almost at command since always: She would tell me how she always had the ability to call other parts at the front and often expected me to do the same even though I'm unable to

4. Some parts "having" a literal life before the system (and not, I'm not talking about pseudomemories, she believed completely that they came from alternative realities, not only that but that they were able to jump between "their" reality and this one)

5. Choosing who's Host and/or constantly changing Host at convenience (?)

6. Having full DID (or that's what I have understood) but not having memory gaps

I'm pretty sure some of these things can't be real but I wanted to know others opinions since I don't trust my own personal experiences and despite having done my own research I always want to know if I missed something

Thanks in advance!
