Cofty,
You will have to ask yourself if everybody in these accounts is wrong because you want them to be wrong.
Or, you might consider they could be right, but it was their subjective experience, witnessed by others, that makes them right.
The problem with doubters in anything supernatural, is that they refuse to consider the possibility that something bigger than themselves might actually exist and they would rather say everyone else is wrong than consider the possibility that there are things that can't be explained away by sleepwalking and meds.
