A NDE can be experienced by anyone, no matter with belief system they have going on. When I had my experience at age 19, it did not make me believe in "god" any more or any less, but it did help me to understand that we human beings know so very little about life and death. I was a very active JW right to this event. It definitely changed me, but it did not frighten me. Afterwards, I "knew" JW's were very wrong and I had lots of questions they didn't wish to address with me.
Any of you that know what enlightenment means or what being spiritual means, understands that concepts regarding "life after death" or the journey of the soul, have nothing to do with religion or a belief in a god. It does however, confirm that we aren't alone, and that our individual souls are connected to a lifeforce/source that exists in the depths of the universe.
Love and Light,
