Language works when we think the same, connecting the words to the same meanings and such. But that never actually happens 100%. It might be closer to 80%. (or if it’s a strange subject, 15%)
So this “conversation” that we’re having here is, to some degree, not actually happening.
But we pretend that it is.
So how much are we pretending? How much of the conversation is hallucinatory conversation?
What we attend to also matters and can shape the second world and what we become conscious of from the first world.
