Some would say all of our consciousness is a hallucination.

I bet if all our brains were wired to constantly see little people, we would adapt and eventually pick up on subtle cues related to the environment or our emotions.

Some student taking an intro to cultural anthropology course would be shocked to find out that some culture has a very different relationship to their little people as she does to her little people. Strangers making small talk on the subway would ask each other what their little people have been up to today. Someone on Hackernews would be reading an article about an herb that can make the little people completely invisible for days.
