These two fatigue-associated subjective states are sleepiness and tiredness. Sleepiness seems to be a phenomenological manifestation of a mentally-fatigued state. A precise definition of sleepiness has remained elusive but Curcio, Casagrande & Bertini (2001) defined it as the state in which there is an increased propensity for the individual to fall asleep. Among the research and definitions there is a tendency to define sleepiness in terms of a state, but some research has investigated differences in trait sleepiness with some success. Trait sleepiness can be described as the characteristics of an individual that influence their experience of sleepiness in a given situation, or “an individual’s starting point from where state sleepiness exerts its influence” (De Valck and Cluydts, 2003).

REM sleep occurs as a person returns to stage 1 from a deep sleep. The function of REM sleep is uncertain but a lack of it impairs the ability to learn complex tasks. One approach to understanding the role of sleep is to study the deprivation of it. Functional paralysis from muscular atonia in REM may be necessary to protect organisms from self-damage through physically acting out scenes from the often-vivid dreams that occur during this stage. Infants spend almost 50% of their time in REM sleep.
Typically the amount of controlness will vary, this often occurs in the middle of a regular dream when the sleeping person soon realizes that they are dreaming (Nichols).

The severity of sleepiness can be quantified subjectively using scales such as the Epworth Sleepiness Scale (Table 1) or can be measured objectively in the sleep laboratory using the multiple sleep latency test (MSLT) or maintenance of wakefulness test (MWT).2 The MSLT measures the physiologic tendency to fall asleep in quiet situations,
