Circadian Rhythm | the biological clock; regular bodily rhythm that occur on a 24 hour cycle |
REM Sleep | (Rapid Eye Movement) sleep; A recurring stage where vivid dreams commonly occur. (AKA Paradoxical Sleep)-muscles are relaxed but other body systems are active |
Alpha Waves | Relatively slow waves of a relaxed, awake state |
Sleep | periodic,natural, reversible loss of consciousness, differ from Unconsciousness (Coma or hibernation) |
Hullucinations | false sensory experiences, seeing something that does not exist |
Delta Waves | Large, slow brain waves that associates with deep sleep |
Insomnia | Problems with falling asleep or staying asleep |
Narcolepsy | A sleep disorder characterized by uncontrolled sleep attacks,may cause one to lapse directly into Rem sleep at inopportune times |
Sleep Apnea | a sleep disorder characterized by a temporary cessations of breathing during sleep and consequent momentary reawakenings |

Latent Content | according to Freud, the underlying meaning of a dream (as distinct from its manifest content.) Freud believed that a dream's latent content functions as a safety valve. |
Rem Rebound | the tendency for Rem Sleep to increase following Rem Sleep Deprivation(created by repeated awakenings during REM sleep) |
Hypnosis | A social interaction in which one person(the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors, will spontaneously occur. |
Posthypnotic Amnesia | supposed inability to recall what one experienced during hypnosis; induced by the hypnotist's suggestion. |

depressants | drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions |
stimulants | drugs (such as caffeine,nicotine, and the more powerful amphetamines and cocaine) that excites neural activity and speed up body functions |
hallucinogens | psychedelic ("mind-manifesting") drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input. |
barbiturates | drugs that depress the activity of central nervous system, reducing anxiety but impairing memory and judgement |
opiate | opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety |
amphetamines | drugs that stimulate neural activity, causing speeded- up body functions and associated energy and mood changes, |
ecstasy (MDMA) | a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but with short term health risks and longer term harm to serotonin-producing neurons and to mood and cognition. |
