+### == Consciousness and Sensory Awareness ==
+
+- Sights, sounds, smells (rain, teacher's voice, pizza in the cafe, etc)
+- Selective attention - focusing on particular stimulus and blocking out any distractions
+- Unusual stimuli ('99), intense stimuli (yellow shirt)
+
+### == Direct Inner Awareness ==
+
+- Poolside, lakeside, oceanside - we are conscious of water before going in
+- Aware of emotions such as anger, of memories of friends, of abstract concepts such as fairness, justice, love, etc
+
+### == Sense of Self ==
+
+- As we grow older, we are aware that we are unique individuals, separate from other people and surroundings
+- "Maevie likes playgrounds" - 3rd person
+
+### == Levels of Consciousness ==
+
+- Preconscious - What did you wear yesterday? Ideas are not in your awareness now, but you could recall them if you had to
+- You can direct your inner awareness or attention to them
+
+### == Unconscious Level ==
+
+- Information stored in unconscious/subconscious is unavailable to awareness under most circumstances
+- Freud
+- Defense mechanisms - we use these mental strategies to push painful memories out of our consciousness. This protects us from feelings of guilt, anxiety, and shame
+
+### == Nonconscious Level ==
+
+- Basic biological functions:
+- Fingernails growing
+- Eyes adjusting to light
+- Blinking
+- Breathing/Exchanging CO2 w/ O2
+
+### == Altered States of Consciousness ==
+
+Sense of self or sense of the world changes
+Sleeping
+Influence of drugs
+Meditation
+Hypnosis
+
+### == Circadian Rhythms ==
+
+Latin: "About/around a day"
+Speaks to bodily changes throughout the day
+Body temp - lowest at 3am-5am
+Late afternoon (4-6) - HC practice - low energy in circadian rhythm
+
+### == Stages of Sleep ==
+
+EEG - bata waves (short and quick) when awake, alpha waves when drowsy are longer and slower
+Stage 1: Light Sleep
+	Brain waves slow from alpha waves to theta waves, dreamlike images (powernap)
+Stage 1 - lasts 30-40 minutes
+Stage 2 - move into deep sleep
+Stages 3-4 - Sleep is deep and the brain produces delta waves - the slowest of the 4 patterns
+Stage 4 - greatest difficulty waking up in this stage
+
+### == Levels of Sleep ==
+
+Half an hour of Stage 4 sleep
+We return to stages 3,2 and 1 (90:00)
+Our heartbeat now rises + we go to REM sleep
+
+### == REM (not the band) ==
+
+Rapid eye movement - dream state
+Go through 5 stages of REM sleep
+Periods of REM get longer as night progresses
+NREM - Non REM sleep
+
+- 9-10:30 - NREM
+- 10:30-10:50 - 1st REM
+- 10:50-12:20 - NREM
+- 12:20-12:40 - 2nd REM
+- 12:40-2:10 - NREM
+- 2:10-2:30 - 3rd REM
+- 2:30-4:00 - NREM
+- 4:00-4:20 - 4th REM
+- 4:20-5:50 - NREM
+- 5:50-6:10 - 5th REM

+
+### == Why do we need sleep? ==
+
+Physical -  Helps to revive the tired body + build up resistance to infection. Keeps the mind sharp
+Psychologically - It helps us to recover from stress, we need more sleep w/ more stressors
+
+### == Gardner Experiment ==
+
+Randy Gardner - stayed awake 11 days
+Became irritable, could not focus eyes, memory, lapses, & speech difficulties
+Film - discusses image of a frog boiling as compared to chronic insomnia
+
+### == Dreams ==
+
+It is during REM sleep that we have the most vivid dreams
+Can be black and white or color
+REM dreams - clear images and plots that make sense
+NREM dreams - plots are vaguer and images more fleeting
+
+### == Freudian View on Dreams ==
+
+Freud - dreams reveal what you really want
+Reveal one's unconscious wishes, fears, and urges
+Some unconscious wishes are unacceptable, perhaps even painful
+Those most likely would appear in dreams, sometimes as symbols
+
+### == Biophyschological Approach - Non Freudian ==
+
+During sleep - neurons fire in the brain that controls movement and vision
+These neuron bursts are random and the brain tries to make sense of them
+It does so by weaving a story - the dream
+
+### == Sleep Apnea ==
+
+Breathing interruption that occurs during sleep
+Do not start breathing until they sit up and gasp for air
+Do not wake up completely, not aware of what happened during the night
+They often feel tired during the day
