Like I said, it's actually very well defined because it's been being studied for decades at this point. Just because it can sometimes be an overloaded term in colloquial usage doesn't negate that.
I again suggest you give the wiki page a read. It's quite in-depth and detailed with plenty of good references.
I did in fact read the Wikipedia page, and also have an A-level in philosophy, which means I've written more about this in three homework esseys than the total length of the English Wikipedia article: https://en.wikipedia.org/wiki/Self-awareness
It's absolutely well defined it's just a complex topic. Most of the examples you gave in your last reply are never defined as self-awareness in an academic paper, e.g. qualia is always separate and the mirror test has always just been an indicator not the thing itself.
