I know it is not "in fashion" today but the description of Megan's illness, resistant to antipsychotics as it was, "arguing with Jesus" calling her self "evil," etc, pretty much matches up with the traditional accounts of demonic possession. Suppose there are anti-human intelligences in another plain of reality and that they can metaphysically sense a "vacant" vessel, like somebody in deep meditation. Such individuals would be at elevated risk of demonic possession.
