• In todays class we are going to look at how
  sleep disorders affect people.

3

• One of my favorite sleep disorders is sleep
  paralysis.
• In Korean it is known as Gawee Nulim.

4

• The scientific explanation of sleep paralysis is
  simple
• (1) Your brain goes into REM sleep.
• (2) Your body chemically shuts down your muscles
  so that you dont move while you are dreaming.
• (3) You wake up in the middle of an REM cycle
  and your muscle and brains are still
  disconnected.

5

• Simple enough.
• But whats interesting is that most people who
  experience this feel an evil presence in the room
  when this happens.
• Many people in fact claim to see a dark shape
  behind them when it happens.
• Nobody ever reports a positive feeling or
  presence when this happens.

6

• In cultures all around the world, people
  attribute this dark presence to be a demon, ghost
  or evil spirit that presses on a persons chest
  and steals their breath.
• In Korea, for example, its a ghost.
• In Turkey, its a Djinni.
• In Eastern Canada its an old hag (evil witch).

7

• In hundreds of cultures around the world people
  report spirits, demons, creatures, goblins,
  succubi and ghosts sitting on people and
  strangling them.

  family and friends. Studies have shown that
  happy people tend to have strong connections with
  family and friends and make time to spend with
  them.

16
Supporting Sentence Details

• Another characteristic of happy people is
  religious beliefs. Believing in something bigger
  than themselves helps people find meaning in
  their lives.

17
Supporting Sentence Details

• Setting goals is a third characteristic of happy
  people. Happy people tend to establish goals for
  themselves in their work and personal lives
  around things that are interesting or use their
  strengths.

18
Supporting Sentence Details

• Surprisingly, having lots of money is not a
  characteristic of happy people. As long as
  someone has enough money to provide the
  essentials for life, having more money did not
  bring extra happiness.

19
Supporting Sentence Details

• High education is also not a characteristic of
  happy people. Studies have shown that people with
  low education are just as happy as people with
  high education.

20
Supporting Sentence Details

• Finally, youth is another feature that was not a
  characteristic of happy people. In fact,
  research has shown just the opposite, that people
  aged 60-64 years old tended to be happier than
  people aged 20-24.

21

• In short, there are characteristics of happy
  people that can be identified, but they are not
  always the characteristics that you might guess.
