I must admit, I haven't looked into the experiences of other voice hearers, but my experience is that the voices can be quite often very convincingly supernatural, as though they are real external spiritual entities. But in my case, not at all nice.
The reasons for this are:
1) Second person narrative. I find this remarkable enough.
2) Turns of phrase or idioms I rarely if ever use, or are not part of my everyday thoughts or speech.
3) Religious narrative that conforms to ideas of the afterlife.
4) Enough plausibility for revealed insights.
However, on this last point, there is also a fair degree of absurdity too.
I realise that for those who are physicalists (only believing in the physical or material reality, and in this respect that mental phenomena are no more than physical brain processes), there is no supernatural and any notion of the "spiritual realm" is nothing more that mental and grounded in brain processes. For such people, something like voice hearing is not supernatural and merely a brain disorder.
But if one subscribes to dualism—not a physicalicists rendering of dualism—then the spiritual is supernatural in nature. That is, it goes beyond the physical brain and is non-material, non-local (in that it does not depend on location, which is a physical concept) and ontologically distinct, such that one can refer to spiritual entities, like "the soul".
Anyway, I respect physicalist views and I think a lot of psychiatrists simply view voice hearing as a brain disorder and nothing more.
For me, I'm open to a supernatural source, but at the same time if I started believing the content of the voices I'd be in a very bad state mentally, in terms of being very frightened. That's how I was when this first began, but thankfully I'm no longer scared, even though the nightmare persists.
