I talk about it to a lot of people, but I'm still not very confident talking about subjects which contradict fundamental beliefs, e.g. objective reality <=> subjective reality.
I have no good experiences with that, because there are a lot of people, who are stuck in their world models and think you must be dumb to believe such things..
(I don't try to convince "denying people", that subjective reality is the TRUTH, but they don't even see it could possibly be real
)
