Penception 

When you are drawing a line within a line within a line, and the line then takes on a life of its own. Eventually the line will be taking YOU for a walk. And then you realize that you are in Penception.

The term became popular with the release of the procedural drawing app "Penception" which makes use of algorithms to interpolate your next line, based on the lines that you have already drawn.

You are in Penception.

Perception 

While our sensory receptors are constantly collecting information from the environment, it is ultimately how we interpret that information that affects how we interact with the world. Perception refers to the way sensory information is organized, interpreted, and consciously experienced. Perception involves both bottom-up and top-down processing. Bottom-up processing refers to the fact that perceptions are built from sensory input. On the other hand, how we interpret those sensations is influenced by our available knowledge, our experiences, and our thoughts. This is called top-down processing.
