REM rebound
REM rebound is lengthening and increasing frequency and depth of REM sleep which occurs after periods of sleep deprivation. When people have been prevented from experiencing REM, they take less time than usual to attain the REM state.[1] When people are unable to obtain an adequate amount of REM sleep, the pressure to obtain REM sleep builds up. When the subject is able to sleep, they will spend a higher percentage of the night in REM sleep.[2]
Sleep-onset REM
Polyphasic schedules, which reduce sleep hours, often rely on the SOREM mechanism, which is an abnormally rapid transition from wakefulness to REM sleep, skipping the period of non-REM sleep that normally characterizes the beginning of the sleep period.[3] After REM debt is accumulated enough, it's common to have SOREM in the beginning of naps or cores, especially close to the REM peak during the dawn hours, which is done by brain to alleviate REM pressure. SOREM is also common for hypersomniac and narcoleptic patients, who generally have excessive REM requirements.
