There are certain spirits whose nature it is, on approaching a person, to rush within their skull, and from there into the spinal marrow, with no other intention and endeavor than to murder him or her. Some such spirits came up to me and immediately rushed into the spinal marrow, saying at once, without the least provocation, that they would suck out the marrows, along with every vital element. And when they had attempted in vain to do this, they tarried within the skull, plotting a variety of schemes, but all in vain. They even propose to take away from the person all the faculty to understand. I plainly felt them present within the chamber of the brain, as well as the attempts they were making, by the resulting pain. I spoke with them, and they were compelled to confess where they came from, who they were and what their nature was.
