Unconscious Dementing
Most users of Dementation realize, on some level, that they don't see the world the same as others. Some are in such denial that they unconsciously force their viewpoint on those who cannot see their truth. Characters with this derangement lace their everyday conversation with powerful uses of Dementation, imposing their own derangements on their victims. The more resistant to the character's ideas the target is, the more likely the character is to unconsciously prove her point with Dementation.
