Imaginary concepts
Imaginary concepts are concepts that we can imagine but do not exist in reality. There is a difference between imaginary concepts and potential concepts. Awarepaths that experience or contain imaginary concepts can be produced in an awarepaducer or by a sensepaducer.
Potential concepts do not presently exist but can exist in this reality. Before the TV or airplane were invented it was a potential concept. But to people that did not believe that the TV or airplane was possible to be made, it to them, was an imaginary concept. Many times the difference between a potential concept and an imaginary concept is the exact definition of the concept. By using one definition of the concept, it may be creatable in this universe, whereas using another definition of the same concept it might not be.
