On an unrelated (or is it?) note, many Old Testament Prophets were described in a way that implied they were having minor "strokes or seizures" when they prophesized. Modern people have had similar experiences in the same medical conditions. There are multiple kinds of "seizures", and many aren't recognized by the person having them. That would conflict with those who claim Jung was schizophrenic (or, the mental disturbance had a medical reason) during those times of gaining new insight.
