Hard questions are often those which contain hidden paradoxes of language, ill-defined conceptual assumptions, not based on anything real. Just because we can form some question, or some predicate, doesn't mean we can actually successfully use it. Instead, we often write many volumes of books, full of delusional thought circles, unable to find clear solution of the paradox; and at its most, blatantly covering the mess with the introduction of some new useless terminology.
Before all, I am not so sure that I am, as Descartes is. I was taught to use the word "I". Didn't imagine it myself. At first I was just seeing images, then they began to have names, until they indicated that I have one too, and thus the "I" time began for me. However, if they didn't do that, it is very possible that I could not even develop the sense of "I". Similar problem is found in some feral children, for example.
I believe, if you could place a human brain in a jar, and give it specific input, you could make it function very intelligently, and never become self-aware at all, thus even unable to comprehend the question in OP. Having this in mind, I'm more inclined to say that such questions are delusional product of false communication, i.e. I kind of fool myself that I am something, because they ask me to.
I hope anybody understands what I mean.
