There can be no mistakes in objects of consciousness, only mistakes about them. To quote Sextus again: “what we investigate is not what is apparent but what is said about what is apparent.”16 In the case of illusions, hallucinations, and other anomalous objects of experience, there is no mistake about them as such. I might see a mirage in the desert. There is no mistaking the mirage itself, that is, the visual experience of a shimmering blur off at a distance. The mistake is to take that blur for a body of water. I might eat a mushroom and watch the trees in the forest dance the tango. There is no mistaking the dancing trees I see. The mistake is to take them for the trees in the forest I saw earlier, that is, for linking them together in terms of some continuous, eternal, substance underlying both. Whenever an anomaly arises among objects of consciousness, it is a clue that we are making mistaken assumptions about the objects in question. If the Pyrrhonists are correct and perceptual illusions are in fact illusions of interpretation and not of perception (appearance), then we have no reason to doubt the phenomena we encounter. And no longer need to assume that the phenomena are somehow subjective. Nor is there any good reason, in their view, to doubt that the appearances I entertain can be entertained by you as well.

Now you made me laught at myself.

I havent finished the book, I was just thinking "the example of the mirrage Ok, the example of the mushroom, well maybe the author should found another example."
The example of the beetle on the video, was the example of letter A in this book and the sound of letter A.
And the prison well, if you adopt pyrrhonism you will get rid of your anxiety and attain the state of ataraxia or tranquility. The metaphor of prison is used in buddhism to refer to samsara and nirvana.Now the author proposes that pyrrhonist ataraxia is buddhist nirvana.
But truly how can you scape the prison with metaphysics?
IMO, his view on pyrrhonism is compatible with buddhism, but buddhism goes beyound that. But well, probably some degree of freedom can be anchieved by skepticism. It can free you from some anxieties created by dogmas and views.
