I can be absolutely certain of my perception and recollection of what my consciousness is experiencing and has experienced.
Note that the truth of this statement does not depend on any certainty about external reality, nor does it depend on certainty that what I perceive or remember is happening or actually happened.
> nor does it depend certainty that what I perceive or remember is what is
It absolutely assumes a unitary conscious experience versus what increasingly seems to be the case, a bunch of narratives our brains thread into a cohesive story ex post facto.
Put another way, there very well may be hard limits to how much a human-like consciousness can understand itself.

That is exactly the reality I am asserting, whether or not they actually describe an "external" reality
I guess my argument is you can’t be absolutely certain about what your internal reality is. Perception, as a measure, even when pointed entirely internally, is fundamentally fuzzy.
My internal reality I hope tracks external reality.
And what I can be certain about is what my internal reality is.
And if you think I cannot be sure of that, I think I can be certain about I think my internal reality is.
And if you think I cannot be sure of even that, I think I can be certain about I think what I think my internal reality is.
It's perception all the way down, recursively. The reality is result of this taken to infinity.
