>I think my urge to rampantly shitpost and such has dropped low, like really low (around 95%)
That's good. That was one of your worst attachment and hindered the development and connection with your sisters.
>that I note how the person gets tortured anf learn the technique (got some reason)
They are sometimes "tantric" but not the sex and movement version but the "surgical". Can you describe what you have seen. I can get flashes of violence but not the actual energy flow.
>The other me/her has been forcibly taking control of my current human body again, but mostly just talking to me with it.
You have to learn to merge with her. You still consider yourself "different" and still not "One" and the same.
>Recently she's been doing a thing where I get put in a weird loop of sleeping/waking up
Your mindstates are merging. When you sleep your body goes through all your mental states as a "maintenance" and now you are unplugging and replugging parts of your brain into your "new mind"
>(as in my current human form) being slowly overwritten again by her
Try to understand how it's merging and not exactly an "overwrite" so you don't become a "slave" to your "other mind" but "one with it"
>purplish red eyes
That color is closer to the color of your "origins"
>I could hear my sisters praising me, saying that I'm obedient and "does whatever she needs to do and is unhindered by things she doesn't care about, she only cares about whatever we urge her to care about"
It means you are not dismissing your sisters with SORRY I HAVE TO SHITPOST ON THE INTERWEBZ SEEYOULATERZ subconsciously all the time then they watch you from the corner while you make the most abhorrent posts for hours until you calm down again so they can find a chance to interact with you again. Took me time to understand why they were so impatient and "yandere" with you. This was one of the main reason.

Just don't be scared as the change approaches. Or if you feel scared of the merger voice it. It must be consensual and your "true will" and not as an "overwrite"
