Ephialtes (illness)[edit]
Ephialtes is a historical term used to describe a condition now commonly understood as sleep paralysis. The term originates from ancient Greek, where it was used to describe a demon or spirit that was believed to sit on the chest of a sleeping person, causing feelings of suffocation and immobility. This phenomenon has been reported across various cultures and is often associated with supernatural explanations.
Historical Context[edit]
The concept of ephialtes dates back to ancient Greece, where it was believed to be caused by a malevolent spirit or demon. The term "ephialtes" itself means "leaper" or "one who jumps upon," reflecting the sensation of being jumped on or pressed down upon during sleep. This condition was often linked to the incubus, a demon in male form who, according to myth, would lie upon sleeping women in order to engage in sexual activity with them.
In medieval Europe, similar experiences were attributed to witches or other supernatural beings. The Old Hag syndrome, a term used in Newfoundland, Canada, describes a similar experience where a person feels a presence on their chest, causing them to wake up but remain unable to move.

Sleep paralysis occurs when a person is temporarily unable to move or speak while falling asleep or upon waking. It is often accompanied by hallucinations and a sensation of pressure on the chest, which can be frightening.
Sleep paralysis is a result of the body entering or exiting REM sleep, during which the body is naturally paralyzed to prevent acting out dreams. When this paralysis occurs while the mind is awake, it can lead to the experience of ephialtes.
Cultural Interpretations[edit]
Throughout history, the experience of ephialtes has been interpreted in various ways depending on cultural beliefs. In some cultures, it is seen as a spiritual or supernatural event, while in others, it is understood as a psychological or physiological phenomenon.
In Japan, the experience is known as "kanashibari," which translates to "bound or fastened in metal," reflecting the sensation of being unable to move. In Nigeria, it is referred to as "Ogun Oru," meaning "nocturnal warfare," and is often attributed to spiritual attacks.
