Why do I feel threatened?

So when you say that the personality of NDErs changes, I agree with you but are the changes actually only modifications on the same personality ? 

My take on this is not to worry about the unknowable, too much, It is what it is and I'm hoping all will be made clear one day. Hope this helps, Dave but I'm fairly certain it won't and I don't blame you

OK, just to clarify what I mean by personality: it is the way we think, behave and interact with those around us and the world in general. I might be described as generally cheerful or grumpy, abrasive or accommodating, generous or miserly, arrogant or humble. These, for me, are personality (or character) traits. They affect how I see the world and what I am likely to believe or reject.

One of my dominant personality traits is fear - particularly fear of death, as I have discussed here before. Some kind of positive experience coming out of a brush with death leading to a loss of that fear would certainly have a big impact on my personality. My identity would remain the same. I would still be who I have always been (in this life, at least). But people would notice a dramatic change in the way I approach life.
