*raises hand* So, having someone watch you... say, do things you would only absolutely ever do if you were completely alone... does not count as a grotesque and horrifying concept?
I would never be comfortable with my own existence again if I knew someone was reading my thoughts without my permission. Ever. That... seems like a life-ruining experience. Imagine every single vague thought that has flitted across your mind unbidden. And now someone knows these unbidden thoughts from a nice little probe into your brain. Things that you have never told anyone. Any secret you have ever promised to keep, that promise is automatically broken. You have zero control over the matter. Whatsoever. There is no way to stop it, no way to fight back.
The mere THOUGHT of it makes me nauseous.
I'm not saying "MIND RAEP" is the perfect term, but... I can see where it's coming from.
