Are Near Death Experiences Real?

The lead story on CNN.com at the moment is titled Doctor says near-death experiences are in the mind. Yet within the story, the doctor calls NDEs "real":

Dr. Kevin Nelson, a neurologist in Louisville, Kentucky, studies near-death experiences and says they're not imagined. The explanation, he says, lies in the brain itself. "These are real experiences. And they're experiences that happen at a time of medical crisis and danger," Nelson said.

Huh? The doctor suggests that an experience explained by brain activity is real and not imagined. There must be other experiences that he'd call unreal and imagined. Where would these imagined experiences come from? Somewhere else, somewhere other than the brain?

We're always faced with big, imponderable questions. What caused the universe? In philosophical discussions, some may say the cause is God, others may say The Big Bang. Neither response resolves anything, as it just pushes the question a bit further down the road. What caused The Big Bang? Who made God?

In the early days of chess-playing computer programs, an interesting problem arose. Say the program could analyze a chess position six moves ahead (a very impressive accomplishment). If the computer was threatened with check-mate, but could make a move that pushed that disaster beyond six moves in the future, it would treat that variation as if the check-mate didn't exist.

Our brain-computers seem to operate the same way. We're faced with a great question of original cause. It can initially be disturbing to realize that we don't know where we came from (and indeed don't know who we are). If we throw in some ideas about Gods or Big Bangs, it pushes the questions a little further away, to a more abstracted level... so we can comfortably pretend that the mystery doesn't exist.

Likewise with claims that "everything is in the brain." If we assume that it all resides in the brain, what have we accomplished? We're left with the slightly more abstracted mystery: in what does the brain exist? Don't know...

We commonly posit two distinct types of phenomena: the unreal ones that exist in the mind, and the real ones that exist outside the mind. Is that true?

Our bodies have skins, so it's easy to distinguish what's inside them from what's outside. Kidneys are inside the body, trees are outside of it. But where is the mind's skin? If we can't locate the mind's skin, how can we say that one thing is inside the mind, while something else is outside it?
