Interesting, and reminds me to ask: children and others, including myself, sometimes exhibit intractable focus or gaze on an object while in a "trance-like" conscious state. It was most common (>50%) among my peers in elementary school, ages 6-12, and eventually resolved on its own for most individuals, causing no adverse or permanent effects. Is this a form of epilepsy? If not, what is it? It was so common, we had a term for individuals "staring" at something and being "out of it" but "aware" for about 15 seconds.
