Akhawayni, Philip Barrough (Elizabethan surgeon and physician during the Renaissance period), Johann Wier, and Isbrand Van Diemerbroeck also postulated that SP was associated with rising vapors from the stomach to the brain. For instance, Themison of Laodicea (1 st-century BC) described SP “nightmare” to be associated with the supernatural being called “Incubus.” Furthermore, a Greek physician Galen assumed SP was in connection with gastric disturbances. Dating back, the term nightmare and SP have been described to be associated with various causes, including science, race, culture, and in fact, superstitions. The activities of neurons in REM sleep are usually similar when an individual is awake, and sometimes, REM sleep may be associated with more neuronal firing, especially in the pons, lateral geniculate nucleus, and occipital cortex.Įarlier researchers have described SP as nightmares since it ranges from seconds to a few minutes and involves episodes of vivid hallucinations and feelings of suffocation or chest pressure. The physiology of REM sleep is associated with increased blood pressure, heart rate, and breathing.

It is one of the most common types of rapid eye movement (REM) parasomnia encountered by the neurologists.

SP has been thought not to affect ocular and respiratory movements, though the limb, head, and trunk movements are affected. believed that Heinrich Fussli's painting of SP in the art “Der Nachtmahr” (The Nightmare) in 1781 was incomparable to the experience in world literature.
