Periodic physiological fluctuations
ex) annual cycles
Biological rhythms
Our awareness of ourselves and our environment
Consciousness
The biological clock; regular bodily rhythms that occur on a 24 hour cycle
Circadian rhythm
Rapid eye movement, recurring sleep stage during which vivid dreams commonly occur (paradoxical sleep)
REM sleep
The relatively slow brain waves of relaxed, awake state
Stage 1
Alpha waves
Periodic, natural, reversible loss of consciousness
Sleep
False sensory experiences such as seeing something in the absence of an external visual stimulus
Hallucinations

Night terrors
Sequence of images, emotions, and thoughts
Dreams
The remembered story line of a dream
Manifest content
Underlying meaning of a dream
safety valve
Latent content
Dreams help us sort out the days events and consolidate our memories
Information processing
Regular brain stimulation from REM sleep may help develop and preserve neural pathways
Physiological function
REM sleep triggers impulses that evoke random visual memories, which our sleeping brain waves into stories
Activation synthesis
Dream content reflects dreamers cognitive development – their knowledge and understanding
Cognitive development
Tendency for REM sleep to increase following REM sleep deprivation
REM rebound
A social interaction in which one person suggests to another that certain perceptions, feelings, thoughts, or behaviors will occur
Hypnosis
Suggestion made during a hypnosis session to be carried out after the subject is no longer hypnotized helps control undesired symptoms / behaviors
