hypnic

Pertaining to drowsiness

Hypnic relates to sleep or the transition into sleep.

A hypnic jerk is the sudden muscle twitch that sometimes startles you awake just as you're falling asleep.

The word appears almost exclusively in this phrase and in medical contexts: hypnic headaches, hypnic hallucinations.
