The Science of Near Death Experiences

Is there evidence that this is something beyond what's going on in the brain? Those are all questions that we need to answer when addressing this. If some one says, jesus told me x y z is true, and that person otherwise seems reliable, and that thing is not taught in scripture, does the church then begin to teach that that's true because we have some one that seemingly has a reliable, testable experience? I don't know what it is, but like ther i just do not like the covers of any of these books  a doesn't make heaven look very attractive,. by bruce grayson.
