freud who were sure you know for his work in
- 00:27
psycho analysis the unconscious the ego super ego in about
- 00:31
a million other things with varying degrees of weird sexual
- 00:33
nous attached to him But he's also well known for
- 00:36
his work on dream analysis In short freud believed dreams
- 00:39
aim to keep the sleeper asleep by fulfilling all of
- 00:42
their wishes that would otherwise awaken them Weird yes but
- 00:46

- 00:48
answer John allen hobson and robert mccarley meanwhile are best
- 00:53
known for their research on rapid eye movement sleep and
- 00:55
their theory explaining the cause of dreams The two essentially
- 00:59
argue that dreams are vaguely cohesive narratives formed by the
- 01:03
brain as a response to the activation of biochemical an
- 01:06
electrical charges that occurred during sleep called the activation synthesis
- 01:10
theory it directly opposes the aforementioned freudian view and instead
- 01:14
suggest the dreams are for the most part random thinks
- 01:17
this simply is the brain's effort to synthesize the random

- 01:36
useful in therapy and ultimately served in drawing connections between

memories and experiences We consciously would not still nothing to

a sleep deprivation So he's not our dream answer That

- 01:53
best known for his focus on sleep deprivation sleep disorders
- 01:57
sleep apnea and narcolepsy Well dement conducted research in which
- 02:01
he prevented participants from experiencing a full cycle of rem
- 02:04
sleep and then examining what happened to their sleep cycles
- 02:08
He found that immediately after being deprived of ram cycle
- 02:11
sleep the participants cycles increased from ninety minutes to one
- 02:14
hundred twenty minutes Funny we had a dream That was
- 02:17
the right answer right before ah mellower Yellow word dream 00:02:21.51 --> [endTime] interrupted
