It begins as a kind of warm fuzziness in the right side of the brain, as though a fissure has opened just above the left eyebrow, running just above the nose, under the right eye and down behind the ear. Sometimes the vision blurs and there is a sense of being pulled down under bathwater. Other times there is a sparking sound in the brain, mental static, the radio in between stations. And the voices robe themselves with wills.
