Rapid Eye Movement Sleep, a recurring sleep stage during which vivid dreams commonly occur. Also know as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active.
Alpha Waves
The relatively slow brain waves of a relaxed, awake state
Periodic, natural, reversible loss of consciousness - as distinct from unconsciousness resulting from a coma, general anesthesia, or hibernation.
False sensory experiences, such as seeing something in the absence of an external visual stimulus.
Delta Waves

Drugs (such as alcohol, barbituates, and opiates) that reduce neural activity and slow body functions.
Drugs (caffenine, nicotine, and the more powerful amphetamines and cocaine) that excite neural activity and speed up body functions
Psychedelic ("mind-manifesting") drugs, such as LSD, that distort perceptions and evoke sensory images in the absence of sensory input.
Drugs that depress the activity of the central nervous system, reducing anxiety but impairing memory and judgment.
Opium and its derivatives, such as morphine and heroin; they depress neural activity, temporarily lessening pain and anxiety.
Drugs that stimulate neural activity, causing speeded-up body functions and associated energy and mood changes.
Ecstacy (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.
Powerful hallucinogenic drug; also known as acid.
