[Heaneisismich]

I suppose you are not asking how a person waking up from a coma remembers his identity (from his memory) but how the sense of self prevails in his mind all the time? Am I right?

Yes, I think that's it.

The question is about how that sense of self kicks in again after somebody has regained consciousness. But again, I am not making any assertions here--I just want to know if this question, or something similar ever came up as recorded in the Pali scriptures. There are people here who are much more familiar with those texts than I am.
