Nightmare
Online Etymology Dictionary
The word “nightmare” (n.) comes from the late 13th century, originally meaning, “an evil female spirit afflicting sleepers with a feeling of suffocation,” compounded from the words night + mare “goblin that causes nightmares, incubus”.
The meaning of the word shifted during the middle of the 16th century from the incubus to the feeling of suffocation it creates.
In the late 1820′s early 1830′s the word was first recorded to mean “any bad dream” and “very distressing experience”.
Associated with the Dutch word, “nachtmare” and German word, “nachtmahr”.
