Transcript of Dreams
by Alexis Miller
dreams: a series of thoughts, images, and sensations occurring in a person's mind during sleep
Rapid eye movement (REM):
You dream about 2 hours every night!
Why we dream:
still don't have solid answer
dream to practice responses to threatening situations
amygdala (flight-or-fight part of brain) is more active during REM
part of brain that practices motor activiy is more active during REM
evolutionary adaption to prepare for flight-or-fight situations
Dreams create wisdom:
brains sort through memories to see which ones are worth keeping
test done on rats- rats were dreaming of important events of the day
dreaming is process in which we separate memories
the more you learn during the day the more you sleep during the night
are like psychotherapy:
dreams reflect emotions
dreaming puts our difficult emotions into pictures
we think through emotional stuff in a less rational and defensive way while dreaming
aren't required to focus on anything in our sleep so our brain can make loose connections, shown through dreams
Sigmund Freud's theory
dreams are representations of unconscious desires, thoughts and motivations
aggressive and sexual instincts find ways into our dreams
found in his book "The Interpretation of Dreams"
The absence of theory:
dreams have no meaning at all
no conscious sense behind dreams
dreams are pointless byproduct of brain firing while we sleep
stage when dreaming typically occurs
signals are sent from the pons to the thalamus and then are relayed to the cerebral cortex
neurons in the spinal cord are shut off causing temporary paralysis
infants spend more time than adults in REM
"REM sleep behavior disorder"
Types of dreams:
animals do dream
have very complex dreams
usually follow the same sleep pattern as us
dream about everyday experiences like humans do
regions of brain that control dreams develop early and become fully functional before birth
spend 50% of time in REM
dream a lot more than adults
can begin to dream as early as while they're in the womb
dreams could be especially vivid because visual cortex is highly active
Dreams have meaning?
highly debated issue
normally people find they are very meaningful to themselves
useful in learning more about the dreamer's feelings, thoughts, behavior, motive, and values
people find that dreams can help solve their problems
artists, writers, and even scientists often get creative ideas from dreams
You forget 90% of your dream!
5 minutes-half your dream is gone
10 minutes-90% of your dream is gone
Blind people dream too!
people who become blind after birth can see images
people who are born blind don't see images, but use their other senses to have dreams
if you don't think you dream, you just don't remember
In your dreams you only see faces you already know!
your mind isn't inventing faces-you see real faces of real people that you have seen during your life but may not know or remember
Not everybody dreams in color!
12% of people dream in black and white, the rest dream in color
4.4% of the dreams of under 25-year-olds are in black and white
Men and women dream differently!
men tend to dream more about other men
70% of the characters in a man's dream is other men
a woman's dream contains almost an equal number of men and women
men have more aggressive
Negative emotions are more common in dreams!
Most people around the world dream about being chased, being attacked, or falling at least once in their life!
