Hori et al. regard sleep onset hypnagogia as a state distinct from both wakefulness and sleep with unique electrophysiological, behavioral and subjective characteristics, [10] [12] while Germaine et al. have demonstrated a resemblance between the EEG power spectra of spontaneously occurring hypnagogic images, on the one hand, and those of both ...
Hypnopompia (also known as hypnopompic state) is the state of consciousness leading out of sleep, a term coined by the psychical researcher Frederic Myers.

The words hypnosis and hypnotism both derive from the term neuro-hypnotism (nervous sleep), all of which were coined by Étienne Félix d'Henin de Cuvillers in the 1820s. The term hypnosis is derived from the ancient Greek ὑπνος hypnos , "sleep", and the suffix -ωσις - osis , or from ὑπνόω hypnoō , "put to sleep" ( stem of ...
In most animals, slow-wave sleep is characterized by high amplitude, low frequency EEG readings. This is also known as the desynchronized state of the brain, or deep sleep. In USWS, only one hemisphere exhibits the deep sleep EEG while the other hemisphere exhibits an EEG typical of wakefulness with a low amplitude and high frequency.
Clouding of consciousness, also called brain fog or mental fog, [1] [2] occurs when a person is slightly less wakeful or aware than normal. [3] They are less aware of time and their surroundings, and find it difficult to pay attention. [3] People describe this subjective sensation as their mind being "foggy". [4]
