Used when confused about how to write from a perspective that differs from the norm in some way.
Maybe this tag could be used on questions for authors who want to write from the perspective of someone who is different than most 'average' people. Maybe they are drunk or drugged, and instead of just using dialogue to show their altercation, the author is writing from their point of view, inside their head. Maybe they are insane.
Maybe the author is unclear on how to do this from lack of experience, conflicting information, etc., so they could tag their question with this so people know their character's POV isn't normal. This could apply to any POV that is altered.
