desires about which we have no true or direct knowledge of.

trained” 24-hr cycle. • Every living thing on Earth has its own circadian rhythm

for the most part based on light and darkness.• We can adapt our cycle if needed. Ex. Working different

shifts at work, daylight savings time, and 24hr of light

experience it once a night or at school..• If you have ever jolted in your seat? Yup, state uno.• Your brain produces Alfa Waves.

Stage 2• More Alfa Waves get progressively slower and disappear • Twilight state • We are relaxing

Stages 3 and 4

• Slow wave sleep.• You produce Delta waves.• If awoken you will be very groggy.• Vital for restoring body’s growth hormones and good

overall health.• From stage 4, your brain begins to speed up and you go to stage 3,

then 2….then ……

And then………..REMMMmmmmmmmm• Rapid Eye Movement• Often called paradoxical sleep.• Brain is very active.• Dreams usually occur in REM.• Body is essentially paralyzed.

mean?• 28% said they had died in a dream• 45% said they had dreamed about celebrities

So why do we dream? Theories •Wish Fulfillment: Sigmund Freud suggested that dreams

provide a safety valve to discharge unconscious wants and desires. That way they don’t come out in our everyday lives• According to Freud there is a manifest content( remembered

story-line) and a latent content or (underlying meaning of dreams)• Ex. Manifest- You are running through an empty school.• Latent- Why are you running through an empty school?

Information processing and organization • Dreams may help sift, sort, and fix the day’s experience in our

memories for future use.• As your brain is organizing the info it may just dump the info it might

find useless and irrelevant.• It is those pieces of random junk that many believe cause those crazy

dreams.

Symbols in dreams

the fear of actually being chased, but rather what we're running from.• Chase dreams help us to understand that we may not

be addressing something in our waking lives that requires our attention.

Death

•Although death is often perceived as negative, it's often more directly related to dramatic change happening for the dreamer.• the end of one thing, in order to make room for something new.

People• Seeing other people in your dream often is a reflection of the

different aspects of the self. • The people in dreams can relate to characteristics that need

to be developed. • Specific people directly relate to existing relationships or

interpersonal issues we need to work through.• Dreaming of a significant other, in particular, is frequently

symbolic of an aspect of ourselves, from which we feel detached.
