Abstraject or Abstrative is an introject that has formed from a part of the perceived world of an abstract media.

Abstract media for this term can be a piece of media that is a collection of random or seemingly not connected things, and/or a media that could be understood in many ways without becoming an alternate universe (AU).

Some examples of abstract sources would be art from Wassily Kandinsky and Pablo Picasso, games like Blaseball and music from artists such as Lemon Demon.
