An Essay on the Incubus, or Night-mare

"An Essay on the Incubus, or Night-mare" by John Bond, M.D., is a medical treatise written in the 18th century. This scientific publication delves into the phenomenon of sleep disturbances known as nightmares, exploring their causes, effects, and implications. It aims to provide a rational understanding of this ailment, which was often steeped in superstition and misunderstood during the time it was written. In this essay, Bond recounts his personal experiences with the nightmare and examines historical perspectives on the disorder, providing insights from ancient physicians to contemporary theories. He identifies various symptoms associated with the nightmare, such as oppressive feelings during sleep and sensations of immobility, which bond claims are tied to physiological responses, particularly involving blood circulation during the supine sleeping position. Furthermore, he explores potential cures and preventative measures, advocating for lifestyle changes and careful diet to mitigate the occurrence and severity of nightmares, thus blending empirical observation with 18th-century medical practices.
