Allot of it has to do with people's individual gifts and inclinations. Some are very sensitive to it most aren't.
Of course I've experienced all sorts..
But when I discuss what I've experienced with those who are sceptical and won't accept it, due to they themselves not experiencing it
I point out that fallacy
And one wY is of course to make them aware just because I cannot hear, I should not assume no one else can hear. This can be stated for any sense of course or even any experience.
Every single culture we have known has had individuals experience what science would dismiss.
I think that's rather foolish
That's allot of humans, spanning all cultures who experience things that are brushed aside.
If it's just an illusion that's a rather large one, rather I think the more time goes on the more clear hard sciences ideological driven agenda will become known and people will start to see it for what it is.
Then again
I see dead people
So...
Thats how I roll
