Hypnagogia is the transitional state from wakefulness to sleep, also defined as the waning state of consciousness during the onset of sleep. Its corresponding state is sleep to wakefulness. Mental phenomena that may occur during this "threshold consciousness" include hallucinations, lucid dreaming, and sleep paralysis.
== Etymology == In 1848, Alfred Maury introduced the term "hypnagogic" from the Greek words ύπνος ("hypnos"), meaning "sleep", and αγωγός ("agōgos"), meaning "conductor" or "leader". Later, in 1904, Frederic Myers coined the term "hypnopompic", with its word-ending originating from the Greek word "pompos", meaning "sender".
