In this disease the patient, in time of sleep, imagines he feels
an uncommon oppression of weight about his breast or stomach,
which he can by no means shake off. He groans, and sometimes
cries out, though oftener he attempts to speak in vain.
Sometimes
he imagines himself engaged with an enemy, and, in danger of
being killed, attempts to turn away, but finds he cannot. Sometimes
he fancies himself in a house that is on fire, or that he is in danger
of being drowned in a river. He often thinks he is falling over a
precipice, and the dread of being dashed to pieces suddenly awakes
him.
