G-Force OOBEs

I think this guy has been mentioned once on these forums but not quite I n relation to this research

He seems to be relating the experiences of pilots to lack of oxygen but could the solution be much deeper?

I'd say that anything that changes/weakens/collapses the brains endogenous em field (neuron firing) increases the chances of an experience, could be blood flow, lack of oxygen, lack of glucose, ketones, cardiac arrest, meditation, event related desynchronisation, drugs etc.

When the brain stops processing it's own em field in a feedback loop, it's sometimes quite happy to temporarily process other external fields.
