This never attacks any one but in their sleep, when the patient lies on his back, and after eating a hearty supper; the patient seems to have a weight on his breast, and strives to speak but cannot: some think they see monstrous shapes, and that a witch or other imaginary beings ride on their chest; whence some affirm they are hag-ridden; however, if any body calls them by their name, or touches them, this sup-posed load immediately vanishes. The best remedy is to eat little or no supper, and to lie with the head pretty high; it frequently affects children, because they eat more than they can digest.
