dreams and sleep

Independent Study- Katie Skrepnek

does everybody dream?

You dream for about 15 minutes to 2 hours every night, but when you think about how long you sleep for (approximately 8 hours) what else does your brain do at night?

Your brain can be just as active while you are asleep as it is while you are awake. It...

  • forgets memories that haven't been re-enforced enough to remember (that's why only studying the night before a test doesn't work!)
  • creates connections between thoughts that can have unexpected outcomes. (why sometimes you wake up with a new idea or remember/figure out something overnight)
  • removes toxins from your brain that have been building up throughout the day from brain activity. They are flushed through the bloodstream to the kidneys and eventually leave the body.

there is a common myth that if someone is sleepwalking, it is dangerous to wake them but it is actually more dangerous to not wake them up. And it's not just humans, animals can sleepwalk this this cat in the video below:

why is sleep so important?

Getting 7-9 hours of sleep every night and having a consistent sleeping schedule is extremely important, physically and mentally. Not doing this can lead or contribute to serious illnesses...
  • diabetes
  • heart problems
  • depression
  • stress
  • weight gain
  • memory loss
  • shorter mortality

is it possible to over-sleep?

Getting too much sleep can be just as risk full as not getting enough sleep and the side effects are pretty similar...
  • diabetes
  • heart disease
  • depression
  • shorter mortality
  • weight gain
  • laziness
  • headaches

what do different dreams mean?

Although certain dreams may mean nothing at all... just your imagination, these are some possible explanations from recent studies


you may not be addressing something in your life that you should be.


related to how much control we have in our lives and whether we are confident enough to achieve our goals.


slow type of falling that reflects the act of letting go of something and falling from a great height reflects something in life that feels very out of control.


related to dramatic changes like the end of one thing to make room for something new.

what is lucid dreaming

Lucid dreaming is when part of your brain is asleep but you are in a way awake so can control your dreams. By questioning reality and realizing something is weird, you can do whatever you want but you still know its not the real world. It's kind of like being asleep but your mind is still fully awake and can control it's dreams.
