I'm liking this, particularly your first 4 chapters; you as an author are kind of single-handedly proving to me that I am capable of enjoying micro voyeur.  And I do agree about the issue involved in "aware" stories; you have a realism hurdle to cross when a loved one of the shrinkies decides to become a mindless slave driver.  I myself find this to be a tough one to deal with.  From this 5th chapter, it seems like your character isn't quite there yet, as she thinks she's crazy, at least for now; personally, I'd say try and leave it at that, you could very easily get some good meat and potatoes out of the story simply on the sister being like "well, it's not real, so why not?".  Wow, this was a long comment, haha.  Anyway good job.

Another great start to another great story. You have a knack for starting us right out in the action without making it feel forced. I'm looking forward to you continuing this and your other works as well.
