IPA: /hɪpˈnɒɡɪk/
KK: /hɪpˈnɑːɡɪk/
Related to the state of drowsiness just before falling asleep.
The hypnogogic images I saw as I drifted off were vivid and strange.
Hypnogogic is formed from "hypnos" (meaning sleep) and "agōgos" (meaning leading or inducing). The term describes something that induces or leads to sleep, often referring to the transitional state between wakefulness and sleep.
Think of 'hypnos' as related to sleep and 'agōgos' as leading — this helps you remember that hypnogogic refers to something that leads you into sleep.
