Summary

Sleep is a state of unconscious rest needed by a wide variety of species across the Arcane Realm, including. 

 

During sleep, most systems in an animal are in an anabolic state, building up the immune, nervous, skeletal, and muscular systems.

 

REM sleep was a stage of sleep necessary to most beings. If a person did not get the acquired amount, there could be repercussions, ranging from depression, exhaustion and hallucinations all the way to a possible psychotic break. Lack of sleep would induce less effective performance and a bedraggled appearance in Humans, although other species might manifest a lack of sleep differently.

 

Androids could, in a manner of speaking, also sleep when they entered a powered-down state from time to time.

 

Sleep Patterns

 

The internal circadian clock promotes sleep daily at night in diurnal species (such as humans) and in the day in nocturnal organisms (such as rodents). However, sleep patterns vary widely among animals and among different individual humans. Industrialization and artificial light have substantially altered the sleep habits or urban races.

 

The most striking differences are between societies that have plentiful sources of artificial light and ones that do not.The primary difference appears to be that pre-light cultures have more broken-up sleep patterns. For example, people without artificial light might go to sleep far sooner after the sun sets, but then wake up several times throughout the night, punctuating their sleep with periods of wakefulness, perhaps lasting several hours.

 

The boundaries between sleeping and waking are blurred in these societies. Some observers believe that nighttime sleep in these societies is most often split into two main periods, the first characterized primarily by deep sleep and the second by REM sleep.

 

Some societies display a fragmented sleep pattern in which people sleep at all times of the day and night for shorter periods. In many nomadic or hunter-gatherer societies, people will sleep on and off throughout the day or night depending on what is happening. Plentiful artificial light has been available in the industrialized regions since at least the mid-19th century, and sleep patterns have changed significantly everywhere that lighting has been introduced. In general, people sleep in a more concentrated burst through the night, going to sleep much later, although this is not always true.

 

Sleeping locations

 

People of many species sleep in a variety of locations. Some sleep directly on the ground; others on nests of leaves and sticks with tree branches; others on a skin or blanket; others sleep on platforms or beds. Some sleep with blankets, some with pillows, some with simple headrests, some with no head support. These choices are shaped by a variety of factors, such as climate, protection from predators, housing type, technology, personal preference, and the incidence of pests.

 

In cities, hotels were businesses designed to provide a place to sleep and stay the night for travelers.

 

Dreams

 

Some species experienced dreams while they slept. During sleep, especially REM sleep, people tend to have dreams: elusive first-person experiences which despite their frequently bizarre qualities seem realistic while in progress. Dreams can seamlessly incorporate elements within a person's mind which would not normally go together. They can include apparent sensation of all types, especially vision and movement.
