It's not necessarily all Neko who I think would experience this, but I would think there are exceptions.
To me, Rin has always been hesitant to partake in the more gruesome duties of warfare. And Miharu has a lot of it, both physically and mentally taxing.
In this 'dreamscape scenario,' the Rin of this world watched not only Ichigo, a close friend, die and not come back, but also Mara, Hinoto and several of her other friends.
Combine this with the supposed 'mind wipe scenario' lurking in the background, and there was potential for some of those afflicted to not come out whole. Perhaps the ST damage was too severe. Maybe Kotori made her that way. Maybe the whole process messed up some wires here and there.
The interpretation is up to the reader, I suppose.

That being said, I wanted to state a few things regarding the nightmare scenario that unfolded over my last two posts. (And thank you to those who gave me thumbs up. It always makes the posts worth it.)
This scenario is, as was proposed by Fred, a 'what if,' and not necessarily how Tom feels about any of the characters in the 'real' continuity.
I felt bad taking control of other characters and writing them in certain ways, but I wanted there to be as thorough as my sleep-deprived mind would allow it.
It's extremely dark not because I wanted to have an angsty time, but because I imagined how a post-mission 'worst case scenario' would come to be. Melisson's influence would only make it easier for Kotori to come out the enemy.
The mental and moral collapse of Tom and Miharu's officers, brought about by circumstances thrust upon them by SAINT. A tainted bargain that would eventually destroy any lasting semblance of unity and togetherness. Even the happiness of the sprites seemed intensely uncomfortable to write, knowing that it was all written for them already.
Nobody occupies the moral high ground in this scenario. By signing a deal with the devil, those in the know sealed their fates. Some made it out better than others.
Unfortunately for Tom and Yukari, they didn't.
