Brain functions during sleep
Memory replay in hippocampal cells during rat’s sleep
(Dragoi & Tonegawa, 2011, Ji & Wilson, 2006)
Hobson’s protoconscious theory
(Hobson & Schredl, 2011)

“If the goal of the brain is to interact with the outside world then why do neurons work so hard when interaction with the outside world is diminished during sleep?” (Buzsaki, 1989)

Dream-learning hypothesis
Sleep functions to integrate our unconscious minds into our daily behavior through dreaming experiences

Loopholes in clinical psychology
Panic disorder
It is not “only a dream”
Our brains react the same way to waking and dreaming stimuli regardless of recall

Implications for study
Lucid dreaming as a therapeutic tool
Controlling one’s mental state during a dream could prevent unconscious strengthening of counterintuitive neural pathways

We spend 1/3 of our lives asleep
Dreaming in REM and non-REM sleep creates a new world for us to develop in
A virtual reality generator

Dreaming has been a fundamental building block for developing people’s attitudes, minds, and behaviors.

Movie night!
Independent variables: exposure to the positive and negative movie
Dependent variables: Linguistic Word Count (LIWC) positive and negative word counts from movie discussion form and dream journal
Repeated measure design with counter balanced order of administration

What we expect
H1: The level of agreeableness will predict the perceived positivity of the movie experience.
H2: The level of agreeableness will predict the perceived favorability of participant’s dreams.
H3: The favorability of dreams will predict the perceived positivity of the movie experience one day after exposure.
