Lots of loaded words in the comments, and hallucination probably takes some of us to places that aren't helpful, but understanding the limits of our perception and understanding gives us better context. Even if we don't understand the limits, it's helpful to know that our reality and reality are separate things. If we don't know we have blind spots, we won't know to check them.

We are all p-zombies, and we voted at our supper club to determine that you don’t actually exist.
