our subjective awareness of ourselves and our environment

a social interaction in which one person (the hypnotist) suggests to another (the subject) that certain perceptions, feelings, thoughts, or behaviors will spontaneously occur

a suggestion, made during a hypnosis session, to be carried out after the subject is no longer hypnotized; used by some clinicians to help control undesired symptoms and behaviors

a split in consciousness, which allows some thoughts and behaviors to occur simultaneously with others

a periodic, natural loss of consciousness — as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation

our biological clock; regular bodily rhythms (for example, of temperature and wakefulness) that occur on a 24-hour cycle

rapid eye movement sleep; a recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active

the relatively slow brain waves of a relaxed, awake state

non-rapid eye movement sleep; encompasses all sleep stages except for REM sleep

false sensory experiences, such as seeing something in the absence of an external visual stimulus

bizarre experiences, such as jerking or a feeling of falling or floating weightlessly, while transitioning to sleep

the large, slow brain waves associated with the deep sleep of NREM-3

a pair of cell clusters in the hypothalamus that controls circadian rhythm. In response to light, the SCN causes the pineal gland to adjust melatonin production, thus modifying our feelings of sleepiness

recurring problems in falling or staying asleep

a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may lapse directly into REM sleep, often at inopportune times

a sleep disorder characterized by temporary cessations of breathing during sleep and repeated momentary awakenings

a sleep disorder characterized by high arousal and an appearance of being terrified; unlike nightmares, night terrors occur during NREM-3 sleep, within two or three hours of falling asleep, and are seldom remembered

a sequence of images, emotions, and thoughts passing through a sleeping person's mind

according to Freud, the symbolic, remembered story line of a dream (as distinct from its latent, or hidden, content)

according to Freud, the underlying meaning of a dream (as distinct from its manifest content)

the tendency for REM sleep to increase following REM sleep deprivation

a chemical substance that alters perceptions and moods

a disorder characterized by continued substance craving and use despite significant life disruption and/or physical risk

the diminishing effect with regular use of the same dose of a drug, requiring the user to take larger and larger doses before experiencing the drug's effect

the discomfort and distress that follow discontinuing an addictive drug or behavior

drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions

(popularly known as alcoholism) alcohol use marked by tolerance, withdrawal, and a drive to continue problematic use

drugs that depress central nervous system activity, reducing anxiety but impairing memory and judgment

opium and its derivatives, such as morphine and heroin; depress neural activity, temporarily lessening pain and anxiety

drugs (such as caffeine, nicotine, and the more powerful cocaine, amphetamines, methamphetamine, and Ecstasy) that excite neural activity and speed up body functions

a stimulating and highly addictive psychoactive drug in tobacco

a powerful and addictive stimulant derived from the coca plant; produces temporarily increased alertness and euphoria

drugs, such as methamphetamine, that stimulate neural activity, causing accelerated body functions and associated energy and mood changes

a powerfully addictive drug that stimulates the central nervous system, with accelerated body functions and associated energy and mood changes; over time, appears to reduce baseline dopamine levels

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

psychedelic ("mind-manifesting") drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input

an altered state of consciousness reported after a close brush with death (such as cardiac arrest); often similar to drug-induced hallucinations

a powerful hallucinogenic drug; also known as acid

the major active ingredient in marijuana; triggers a variety of effects, including mild hallucinations
