"The hypnagogic state is that heady lull between wakefulness and sleep when thoughts and images flutter, melt, and transform into wild things," wrote Boston Globe correspondent Cate McQuaid (October 1, 1998). Some scientists have attributed alien-abduction stories to this state, but for most people these "half-dreams" are entirely innocuous. Perhaps the most famous hypnagogic dream is that of the German chemist Friedrich August Kekule von Stradonitz, who was inspired with the concept of the benzene ring by a vision of a snake biting its own tail. You're not dreaming if the Greek root hypn-, meaning "sleep," seems familiar—you've seen it in hypnotize. The root -agogic is from the Greek -agōgos, meaning "inducing," from agein meaning "to lead." We borrowed hypnagogic (also spelled hypnogogic) from French hypnagogique in the late 19th century.

Note: The word hypnagogique was introduced by the French scholar and physician Alfred Maury (1817-92), apparently first in print in the article "Physiologie psychologique des hallucinations hypnagogiques, ou des erreurs des sens dans l'état intermédiaire entre la veille et le sommeil," Annales médico-psychologiques, tome 11 (1848), pp. 26-40. Maury introduces the word as follows: "J'ai donné l'épithète d'hypnagogiques (1) aux hallucinations qui forment la matière de cet article, parce qu'elles s'offrent presque toujours comme les précurseurs du sommeil, et qu'elles l'amènent en quelque sorte …[footnote] (1) C'est-à-dire qui amènent le sommeil, de ὕπνος, sommeil, et αγωγός, qui amène." ("I have given the name hypnagogic (1) to the hallucinations that make up the subject of this article because they almost always present themselves as the precursors of sleep, and because they in a way lead to it …[footnote] (1) That is to say, which bring on sleep, from hýpnos, sleep, and agōgós, that brings on.")
