Some of our favorite near death experiences are reported by atheists, skeptics and non believers.
Not because they are converted to religion of course thereafter. But they DO seem converted to the idea, by dint of personal experience, that we do HAVE A SOUL that continues on after the death of the body.
Here is a very cool NDE that happened earlier this month, and was reported to NDERF.org in late August, shortly therafter. (she describes herself as an atheist prior to the experience)
