knowledge

There is a difference between knowing something and thinking I know something
Like knowing how to drive is different than thinking that I know how to drive
Like there is a difference between being happy and thinking that he is happy
usually, an unhappy person think and wants to be happy
knowing something is like unconscious competence, knowing without knowing
thinking that I know something is conscious competence
habit, competent skills.

Is suffering only problems of knowledge? Having false knowledge? not seeing illusion? thinking of appearance as real? getting lost following the wrong map?
To know something is to recognize form and name
however, there is a difference between recognizing (familiar) and knowing
Dejavu is recognizing (familiar) without knowing
the opposite, jamais vu, is knowing but not recognizing
preque vu is almost remembered something, the tip of the tongue

To rephrase, to know something is to have an idea of appearance of a form (photographic) and name
We also create names of qualities to describe the objects, relationship between objects
