You have learned to master your insanity to a certain degree. You still experience them, but you can usually distinguish between what is real and what is not. You also have authority over your own abilities, even when you are just a voice in someone’s head. You can decide whether they can access your powers or not.
This prevents you from being distracted in situations that require focus and concentration, such as combat. You can even ignore your hallucinations when they are not helpful. You can also lead a relatively normal life to a certain degree, although others might think you are a bit of a daydreamer. However, you do not have complete control over your insanity. It can still flare up at random times, causing you to lose touch with reality.
(Taking Wonderland allows you to possess Well-Adjusted together with the Hallucination Insanity Options.)
