Here's the thing: in order to wow a skeptic, you need to be able to prove that whatever happened cannot be the result of what's known.
We know about the hallucinatory effects of altered brain chemistry due to:
Fever
Infection
Injury/trauma
Medicine (including anesthesia)
Oxygen deprivation
Alcohol
Drugs
Shit, even things like sleep paralysis
So, the burden is on the person sharing their story to prove that their visions weren't due to one of the multitude of rather mundane causes listed above (and I probably missed one or two). And none of them do because it makes their fantastic narrative, and the product they're trying to sell based on it, utterly un-fantastic. It cuts the legs out from under the sales pitch.
Logic dictates that the simplest answer is likely true. In lieu of real evidence, the things I mentioned above are far, far more likely as being the cause of the visions than anything else.
