In contemporary parlance the word “nightmare” conjures up images of a scary dream that leaves us shaken and afraid. This fear usually subsides when we wake and realize that we are actually safe in our own bedroom. However, the original conception of the “Nightmare” was much more vivid and terrifying, even seen as potentially deadly.
Before the early 20th century when this semantic shift began, the Nightmare had a much more specific meaning in medical and non-medical literatures. A paradigmatic episode of Nightmare consisted of: (a) paralysis of the entire body except for the eyes, (b) conscious awareness of one’s surroundings, (c) a feeling of weight on the chest, (d) an inability to cry out for help, and (e) extreme terror. The terror during Nightmare was due not only to inescapable paralysis, but also to the perception that someone (or something) was pressing down on and assaulting you. Specific cultures experienced this attacker differently (e.g., incubi/succubi in Rome;1 giant bats in Zanzibar),2 but were unanimous in the frightening nature of this nocturnal assault. The famous painting by Henri Fuseli3 is perhaps the best visual representation of this phenomenon.
Etiological theories for the Nightmare were far-ranging. Perhaps not surprisingly, it was viewed by the lay public as an actual attack by supernatural beings (demons, witches, or vampires).4,5 Thus, Nightmare sufferers were victims of obsession (viz., tormented from the outside as opposed to possession, which is torment from within) from a night-fiend with malevolent and often carnal intent. Various preventive measures such as sleeping with a bible6 or salt under one’s pillow7 were derived from this theory, as evil beings were presumed to detest both.
Physicians from the ancient world to early modernity and beyond eschewed supernatural forces in favor of naturalistic explanations for the Nightmare. When reading these source materials, it is surprising how little theories and treatments changed over five hundred years. Ancient Romans would have certainly recognized and understood the palliative efforts of nineteenth century physicians and vice versa. Using the categories available to them at the time (e.g., humoural theories), they located the origin of Nightmare in somatic causes such as a plethora of blood8,9 or digestive distress.10 Treatments logically followed from theory and included venesection, purgatives, and dietary changes (thinning the diet, reducing body acidity, ingestion of aromatic herbs).8,10-12 Interestingly, treatments for Nightmare were very similar to those for “the sacred disease” of epilepsy.
Some physicians claimed that Nightmare could be a prelude to more serious diseases (e.g., epilepsy, apoplexy) and even lead to death.9,11 Silimachus, a Roman follower of Hippocrates, described Nightmare spreading like a plague throughout Rome and resulting in the death of many citizens.11 The veracity of Silimachus’s claim, however, is clearly suspect.
So where does the Nightmare fit in contemporary psychology and psychiatry? Today, it would be conceptualized as a subtype of sleep paralysis. Sleep paralysis is a common feature of narcolepsy (part of the “narcoleptic tetrad”) and certain seizure disorders, but often occurs alone.13 Recent empirical work found it is common in psychiatric and non-psychiatric samples14 and is associated with a number of psychiatric symptoms, sleep patterns, and pre-existing beliefs.15,16 Much work has been done cataloging the more typical sleep paralysis hallucinations,17 and they do in fact dovetail nicely with descriptions of the Nightmare in folklore and myth. Unfortunately for contemporary sufferers, treatments for sleep paralysis are not yet well-articulated, but REM-suppressing antidepressants may be useful.18
Does the Nightmare persist in contemporary mythologies? Interestingly, and in spite of the fact that sleep paralysis is a fairly well-described REM-based phenomenon that has attracted popular attention, the Nightmare indeed continues. Most notably one can see present-day reinterpretations of the Nightmare in alien abduction narratives.19 Common abduction scenarios include an inability to move, abject fear, feelings of suffocation, and attacks/probings/surgeries when in a prone, defenseless state. The Nightmare also likely plays a role in nocturnal encounters with ghosts. More recently, popular press attention on “shadow people”20 may also be related to the Nightmare/sleep paralysis. Shadow people are indistinct humanoid shapes often seen at night and in the periphery of one’s field of vision.20 These nocturnal intruders are alternately claimed to be the visual manifestations of astral projection or inter-dimensional beings. Thus, as with extraterrestrials, a science fiction element may be operative here as well.
In closing, the Nightmare has undergone significant modification from a malevolent, dangerous, real-world attacker in possession of paranormal powers to the much more feeble and anemic scary dream that we know so well today. However, as with most experiences possessing personal and historical significance, the Nightmare and pockets of earlier beliefs persist to the present.
