I'm getting a lot of that from litewave's posts.
What I'm seeing is a lot of hasty assertions and generalizations, followed by ineffective backfill attempts at post-justification. For example, he's trying really hard to make the Wikipedia summary of French sound like what he intended all along, even though it patently isn't if you actually read the chapter.
But in all fairness, how can patients describe what they experienced except in experiential terms? Try, for example, to describe the smell of something -- anything -- without comparing it to another thing.
What we describe informally as an "out-of-body experience" (OBE) is a collection of reported phenomena that sometimes get called things like contextual dissociation in the neurology literature. There is no one agreed-upon term, either in the technical or in the popular vocabulary. As far as the spectrum of actual reports goes, some report a simple feeling of being nowhere, or a general feeling of detachment. Certainly the spectrum includes people who say, "It seemed like I was floating above my body." But it's important not to preferentially sever these specific reports from all the dissociation reports and give them special significance.
Another thing neuroscience reminds us is that we have no metasensation properties in the brain. Fans of
The Simpsons may recall the episode where Dr. Nick asks, "When you were in that coma, did you feel your brain getting damaged?" Hilarious, yes, but that's pretty much what critics of the neuropathological explanation for NDEs want us to expect. Instead neurologists remind us that when things go wrong in the brain, it's always perceived in terms of sensory inputs because that's the only way the brain
can present information to the cognitive layers. It's not like people suddenly grab their heads and say, "Ow! My amgydala!"
If something goes wrong with, say, the central vestibular system, it's not like there's a light that flashes in the cognitive layer saying, "GIMBAL LOCK." No, you might just have the sensation of being off balance, even when your body is balanced -- or of being perfectly balanced when you're about to fall over. Trauma or dysfunction in the sensory conditioning areas of the brain have no out-of-band method of reporting to the conscious perception. Similarly there are areas of the brain that keep track of where the various parts of our body are. When those areas are affected abnormally, the result is a
sensation of not knowing where your body is, not some special indication that we consciously interpret as something wrong elsewhere in the brain.
"It seemed like I was floating above my body" doesn't necessarily translate to, "I literally believed my soul had left my body and was floating above it." People report their NDE observations as sensations because at the cognitive level they are indistinguishable from actual sensations. That certain researchers choose to take the reports literally is no indication that the patients themselves did.
