Transcript REM sleep
SLEEP Sleep stages are defined in terms of brain-wave patterns, which are measured by an EEG – the sticky pads all over your head that record electrical activity in the brain. *if you have any…-_-** There are two (2) major types of sleep REM sleep, a stage of sleep characterized by rapid eye movements, a high level of brain activity, a deep relaxation of the muscles and dreaming This is the time when we will dream. “Active sleep” 15 minutes (beginning of night) to 45 minutes (end of night) Your voluntary muscles are paralyzed. -Why do you think this is? NREM sleep. This stands for non-rapid eye movement and is the other type of sleep. Where we spend the majority of our sleep time Divided into 4 stages (first four) Decreases in length as nights’ sleep progresses. “Quiet sleep” NOT TOO QUIET….. Bed-wetting, sleepwalking, and talking in one’s sleep all occur during NREM sleep. How many different stages do you see? Where is REM sleep located? NREM NREM NREM NREM REM SLEEP Now something strange happens - breathing is irregular - blood pressure rises - heart beats faster - you have entered REM sleep (Rapid Eye Movement) During a typical 8 hour night people move through the stages 5 times, with each passing REM sleep stage becoming longer and longer. (up to 45 minutes or a little longer) Sleep paralysis Lucid dreaming Sleep Learning • We might not be able to learn while we are UNCONSCIOUS, but by getting ENOUGH sleep we can help ourselves LEARN WHILE CONSCIOUS. Theories on WHY we Sleep We Sleep to Rest • We are highly active during the day and we use a lot of energy so AWAKE is only a temporary state. We are awake to feed and reproduce. • We sleep to gain relief from this highly active state so we can function normally both physically and mentally while awake. We Sleep to Heal and Grow • Sleep also allows us to physically heal our bodies. This is marked by the constant growth and repair of the body's immune and nervous systems, as well as our muscles and bones. We Sleep to Learn • Sleep may help the human brain get better organized - by filing away important memories and discarding unwanted information. • Other sleep experiments have shown that procedural memory (your ability to perform certain skills) is dependent on REM sleep. Similarly, declarative memory (your knowledge of facts) relies on getting enough NREM Sleep. • In a study by Turner et al, 40 people were allowed only 26 minutes sleep per night. They were given cognitive tests which showed their working memory deteriorated by 38% over four days. Without REM sleep, they found it much harder to complete memory tasks and solve problems. We Sleep to Dream • Everybody dreams, every night (even if you don't remember them). Dreams are an expression of our unconscious thoughts and conscious experiences. They are so important that if we are seriously sleep deprived, we actually start to dream while awake. An Overview • See you in my altered state of consciousness 5 stages of sleep review • 1.

DREAMS Controlling your dreams!!! • http://www.youtube.com/watch?v=lYSX51xBk os Why do we dream ted-ed • Ted-ED Did you know? • Dreams have been a mystery for philosophers, poets, scientists, and many others for centuries • Dreams can be in black-and-what or in full color. • People who go blind after seven years of age do report visual dreams in the same way we perceive them. It seems the longer you experience the world with sight, the longer you will go on dreaming visually. Someone who goes blind in their senior years can experience vivid dreams for many years after losing their sight. • People born blind will experience dreams in forms of their other sensations, but emotionally their dreams are very similar to the seeing. More nightmares though, thought to be because of fears-dangers When and How Long? • We have our most vivid dreams during REM sleep. – These are usually the dreams that feel very realistic, and we can sometimes recall exact information – Our REM dreams usually take place in real time. • 10 minutes = 10 minutes • During NREM sleep, plots are vaguer and images are less clear/obvious. Remembering? • It is very difficult for humans to recall their dreams because they are moving between levels of consciousness. (moving from sleeping to awake) What if we could watch what we were dreaming? • http://www.youtube.com/watch?v=wgxJhpLo FFU Function of Dreams • Freudian view (for test) – Said to be the Father of Psychoanalysis (what is driving our behavior) • Dreammoods.com (for test) – Phone app Sigmund Freud • “Dreams are the royal road to the unconscious” • Freud was the first theorist in the modern era to argue that dreams are an important part of our emotional lives. • Dreams contain clues to thoughts and desires that are hidden in our subconscious. Freudian View • Freud called the actual dream content the MANIFEST content • Freud said that the manifest content was used to hide the actual deep, dark secrets of our dreams. The manifest content is thought to disguise the LATENT content. (hidden messages from the subconscious) Freudian Way • Manifest content is listed (actual dream) • Dreamer associates the manifest content with what they ACTUALLY believe the content means! – While thinking of associations the dreamer does not sit and think hard about this, it’s the FIRST thing that pops into their consciousness when thinking of the dream symbol. How do we tap into the latent content? • Free association – Write down all the symbols from your dream in a column – One by one go through the symbols and picture them each individually – Right when you picture the symbol, write down the FIRST thing you think of • Freud said these free associations come straight from our subconscious mind. – Example- RED….? Baird Dream Circa 2015 • I was sleeping in my childhood house, but the house was located at my current residency. I woke up and looked out my window to see a car (trucks) chase through the golf course. The trucks were not on the grass at all but instead on the gravel pathways.
