《论衡·卷二十二·订鬼篇》
病人病得厉害身体疼痛，就认为是鬼拿鞭子棍棒殴打他，或者是见鬼拿槌子锁链绳索站立守候在他的身旁，病痛中恐惧，虚妄地看见了鬼。
病者困剧身体痛，则谓鬼持棰杖殴击之，若见鬼把椎锁绳纆立守其旁，病痛恐惧，妄见之也。
The patient is seriously ill with pains throughout the body and believes it is ghosts punishing him with whips and sticks, or ghosts holding hammers, chains and ropes standing guard by his side. Being in great pain, he is frightened and hallucinates ghosts.
