Whether these bits of knowledge are worth believing is another question entirely. If your perceptions are being fooled is not known, but what you perceive is known.
Some of these assertions are questionable but in general it's saying your experience is what it is.

Any idea that an experience (or any future recollection of it for that matter) is reflecting an objective 'truth' with a high degree of fidelity is provably false, the simplest example of that being an optical illusion. A more subtle examples would be the kinds of fine motor adjustments people make that occur before they are consciously aware of either the need to make them or the fact that they are making them.

Moreover, knowing what you are thinking does not imply you know why you're thinking it at a basic level. A lot of thought is reconstructive in the sense that it amounts to the thinker trying to convince themselves they are a sensible being living in an understandable world, interpretable within their frame of reference..
