What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[Angrboda]

You mean she didn't remember anything between the time of her NDE and the time of her heart being restarted?  Oh say it isn't so!  It couldn't have anything to do with the fact that she was under anesthesia and basically dead, could it?  The parts of her NDE which can be correlated with events in the operating room clearly occurred while she was fully conscious.

Are you saying she was fully conscious during  the entire operation? Her eyes were taped shut and she was still able to describe surgical instruments and the surgical procedures used on her.
