Could the existence of such cultures, throughout evolution, be the reason that some hear voices, or have developed other mental illnesses?

There's the theory of the so-called "bicameral mind":

That's an interesting theory, in a lot of native cultures, voices (whether it be auditory or in dreams) seem to play a significant role.

I've had about 3 experiences happen to me that I don't know how to explain, 2 were what you'd call auditory hallucinations and one was a thought that popped into my head that ended up coming into fruition immediately after.

"one was a thought that popped into my head that ended up coming into fruition immediately after"

Isn't that survivorship bias? I presume you've had other thoughts about possible scenarios, and they were presumably wrong?

To put it another way. I've experienced deja vu, and rationally I know the thing hasn't happened before, so I don't mention it. But you are mentioning it, suggesting theres more to it?
