Scientists have also suggested that the brain may temporarily rearrange itself by inhibiting normal brain activity and immediately creating new biologically stable brain connections. This, ultimately, makes it harder to determine reality from fantasy and amplifies your intensity of thought which makes planning ahead and self conscious thinking almost impossible.
That’s an acceptable description of ego death. The reference to 'inhibiting normal brain activity and immediately creating new biologically stable brain connections'
means, to me, that the brain/mind system is finding other stable methods of generating consciousness without reference to the strongly reinforced habit of fixedly associating all thought with an internalised construct of a conscious self.
