Ok, so one of the main characteristics of Ink's Insanity is that it literally makes no sense half the time. One of the things I think adds to that are Dreamscape doors. The earliest form of this was in II S1 P2 when Ink opened a door to a bad memory. A Dreamscape door is a door that leads to a dimension consisting of the creator's dreams, and nightmares. There are some characters that came from the Dreamscape doors including Neck, Bird, Fish, and Cat, all composed of nightmares. I will go into detail on those characters in another project.
