Hypnopompia (also known as hypnopompic state) is the state of consciousness leading out of sleep, a term coined by the psychical researcher Frederic Myers.Its mirror is the hypnagogic state at sleep onset; though often conflated, the two states are not identical and have a different phenomenological character.
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 hypnopompia –sleep to wakefulness.)
The first issue at hand is our circadian rhythm — our body’s natural pattern of sleep and wakefulness. Every animal (humans included) has a rhythm that, when followed, allows it to function ...
Just to add, the abstract of another article points out: "Hypnagogic and hypnopompic hallucinations are visual, tactile, auditory or other sensory events, usually brief but sometimes prolonged, that occur at the transition from wakefulness to sleep (hypnagogic) or from sleep to wakefulness (hypnopompic)."
This state is sometimes referred to as relaxed wakefulness. [4] Alpha waves disappear and the theta wave appears. People aroused from this stage often believe that they have been fully awake. During the transition into stage-1 sleep, it is common to experience hypnic jerks. [5] Stage 2 – no eye movement occurs, and dreaming is very rare. The ...

[2] Being awake allows the person to not only be aware of themselves and the world, but also to have conscious motor coordination and understand the difference between need and want that comes from ...
Cortical activity gets progressively disrupted during wakefulness and sleep restores the levels of cortical activity close to criticality. [128] Signal noise affects many aspect of the central nervous system. [129] Understanding the relationship between wakefulness and entropy can be approached from the field of statistical mechanics.
