Hypnic

Relating to or occurring during sleep or the onset of sleep. It describes phenomena experienced in the transitional state between wakefulness and slumber. This includes sensations, hallucinations, and physiological changes unique to this phase, often characterized by muscle twitches, visual imagery, and a sense of falling or floating. The hypnic state is distinct from both wakefulness and deeper stages of sleep, holding a unique blend of conscious and unconscious experiences. It's a fascinating area of study within sleep research, offering insights into the brain's activity during this ephemeral period.
