Cathemerality, sometimes called metaturnality, is an organismal activity pattern of irregular intervals during the day or night in which food is acquired, socializing with other organisms occurs, and any other activities necessary for livelihood are undertaken.
Hypnagogia (from Greek hypnos "sleep" + agōgos "leading, inducing") is the transitional state between wakefulness and sleep (i.e., the onset of sleep), originally coined in adjectival form as "hypnagogic" by Alfred Maury.
The equivalent transition to wakefulness is termed the hypnopompic state. Mental phenomena that occur during this "threshold consciousness" phase include lucid dreaming, hallucinations, out of body experiences and sleep paralysis. The collective noun "Hypnagogia" was coined by Dr Andreas Mavromatis in his 1983 thesis (Brunel University) which was later published by Routledge (hardback 1987, paperback 1991) under the title "Hypnagogia" the Unique State of Consciousness Between Wakefulness and Sleep and reprinted in a new paperback edition in 2010 by Thyrsos Press. The term "hypnagogia" is employed by Dr Mavromatis to include both sleep onset and the transition from sleep to wakefulness; he retains, however, the adjectives "hypnagogic" and "hypnopompic" for the identification of specific experiences.Somnolence (or "drowsiness") is a state of near-sleep, a strong desire for sleep, or sleeping for unusually long periods (c.f. hypersomnia). It has two distinct meanings, referring both to the usual state preceding falling asleep, and the chronic condition referring to being in that state independent of a circadian rhythm. The disorder characterized by the latter condition is most commonly associated with users of prescription hypnotics, such as mirtazapine or zolpidem.
It is considered a lesser impairment of consciousness than stupor or coma.
