No it's not shocking. Your theory is interesting, but there remains several problems:
- generalization problem... all NDE OBEs must be generated via this mechanism... people have already pointed out there's a huge variety of different cases, it seems we're falling into a maslow-hammer type of logic.
- vagueness problem... there's not enough specificity in the proposed mechanism to clarify what are its limitations; what we could expect to be originated by it and what falls outside
- lack of fundamental evidence... that the phenomena can indeed transmit perceptions remotely in a variety of injured brains...
I think anyone who has looked into the NDE literature and research wouldn't put all stakes on something this tentative.
External patterns lead to internal patterns. Or another way to say this is that external patterns, are relayed to the brain, and result in correlated neuron firing.
I'm simply saying that these fields from third parties neuron firing can sometimes be detected by a brain that has had a reduction in the the power of its own endogenous field... say perhaps from a few feet away.
The experients brain can therefore temporarily use sensory data from a third party, in addition/instead of data from their own senses where available.
The brains physical network is therefore intersected by a complex pattern of field shapes. Where they intersect the network results in a pattern of activation. These patterns of activation must allow coherent interference (quantum), and it's here where I think conscious experience probably arises.
Most of the distant veridical type OBE's seem to be with relatives, friends, loved ones, who I suspect already have similar networks.
So that allows 1) a localised effect from third party strangers who can lay down their own field pattern on an adult patients exposed network, 2) a localised, or distant effect with friends, family, loved ones because the adult patients networks are already similar. 3) a mixed effect in children, where they can experience both strangers and loved ones both localised and distant, because their networks are not fully formed/still forming and because of this, they have greater compatibility (less uniqueness) than an adults network.
That's the best way I have been able to think about it (I haven't got the foggiest if it's correct) but I do find it a useful way to understand these experiences.
Not a particularly comprehensive reply, but I don't want people to get the idea that these fields I'm talking about contain the conscious experience... They don't, as far as I can make sense of things. They are just a way of activating the networks themselves... and that pattern of activation leads to some other mechanism (coherent interference I suggest) where the actual conscious experience probably comes into being.
