Rather than invoking something that leaves the experiencers body as an explanation for the verifiable OBE portion of the NDE. It’s possible that these experiences might involve the use of third party/ies eyes, or, more accurately third parties conscious awareness. Using conscious awareness offers a possible explanation for the common lack of body, and field theories of consciousness (McFadden, Pockett) make a lot of sense to me.
It’s also worth bearing in mind, that these experiences are not always seen from a ‘floating’ type perspective, some are also seen from a ‘first-person’ perspective. In the diagram above, fields from multiple third parties create the commonly recalled floating experience. However, just a single third party would produce a first-person perspective.
Henrik Ehrsson’s work may offer some explanations for this. He seems to demonstrate properties about our location of ‘self’.
1) shifting of self-location in space.
2) the difficulty the brain appears to have in perceiving the ‘self’ to be located at two different places at the same time.
I’m open minded on type of fields, but EM fields are an interesting example, because we’ve known since 2010 that neuronal networks are probably affected by the very EM fields they create when firing – creating a feedback loop. Here’s a link to the paper Frohlich & McCormick (2010). Here’s a link to a more readable article: Cortical Call Out: The Brain’s Electric Field Creates a Feedback Loop That Synchronizes Neural Activity.
It seems logical – at least to me – that this research indicates the brain might therefore be affected by external fields, particularly if the fields are similar to the ones the brain usually produces itself.
These fields are arguably one of the best correlates of consciousness we currently have, and they are also strongly suspected to be involved in laying down memories. Modulation of local field potentials in the V1 and V2 visual areas of the brain have also been shown to correlate with perception. We also have real problems explaining our normal visual experience of reality without some way of binding these synchronously firing neurons together, its long been suspected they might be bound together by fields.
