I've seen a lot of conflicting statements about what is or isnt a mental shift. Some have said it's any kind of animalistic reaction to a stimulus (eg. Growling or snapping at someone who surprises you) and others have said its practically complete immersion in your kintype's mindset (eg. No human thoughtsamd foraging for food). I know there are varying intensities possible, but I was wondering if someone could clear up the boundries of this kind of shift for me.
