    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
  10. Alpha Waves
    the relatively slow brain waves of a relaxed, awake state
  11. sleep
    periodic, natural, reversible loss of consciousness--as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation
  12. Hallucinations
    falso sensory experiences, such as seeing something in the absence of an external visual stimulus

  15. Narcolepsy
    a sleep disorder characterized by uncontrollable sleep attacks. The sufferer may laps directly into REM sleep, often at inopportune times
  16. Sleep apnea

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

  25. Psychoactive drug
    a chemical substance that alters perceptions and moods
  26. Tolerance

  30. Addiction
    compulsive drug craving and use, despite adverse consequences
  31. Depressants
    drugs (such as alchohol, barbituratesm and opiates) that reduce neural activity and slow body functions
  32. Barbiturates
    drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgement
  33. Opiates
    Opium and its derivatives such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety
  34. Stimulants
    drugs (such as caffeine, nicotine, and the more powerful amphetamines, cocaine, and Ecstasy) that excite the neural activity and speed up body functions
  35. Amphetamines
    drugs that stimulate neural activity, causing speeded-up body functions and associated energy and mood changes
  36. Methamphetamine
    a powerfully addictive drug that stimulates the central nervous system, with speeded-up body functions and associated energy and mood changes; over time, appears to reduce baseline dopamine levels
  37. Ecstasy (MDMA)
    a synthetic stimulant and mild hallucinogen. Produces euphoria and social intimacy, but with short-term health risks and long-term harm to serotonin-producing neurons and to mood and cognition
