2. Why are dreams important?
• Rich history across most cultures
• Royal road to the unconscious – Freud
– While opened up dreams as important, he also
pathologized them
• With discovery of REM sleep and the sleep
laboratory, dreams entered science
• While not local only to REM, those that are
most recalled and most often puzzled about
are typically REM dreams
3. Why are dreams important?
• Function of dreams increasingly clear
– Evolutionary threat/play (Revonsuo; Humphrey)
– Emotional Regulation, especially negative
emotions (Kramer; Nielsen; Zadra)
– Memory integration & consolidation (Stickgold)
– Problem-solving, creative inspiration (Barrett)
– Metacognition (LaBerge; Kahan; Kahn)
• All this serves personal and interpersonal
needs if shared and processed
4. • Media saturated society
– Video game play represents the most immersive and
interactive media experience
• Isn’t it all just incorporation?
– Yes gamers dream about games
– And no,
• Example of value of studying gamers dreams...
Why study gamers dreams?
Gamers dreams show fundamental
structural differences
5. Presence in Games and Dreams
• Dreams have been called the “gold standard”
for presence (sense of being there) in VR and
games (Revonsuo; Moller & Barbera)
• Never measured until now (Gackenbach &
Rosie, 2010)
– Played Mirror’s Edge before sleep in lab
– Gathered dreams for next two weeks
– Presence measured after game and after dreams
6. • Presence sum score NO DIFFERENCE
• Items (12) got 4 differences 8 NO DIFFERENCE:
– The dream/game caused real feelings and emotions for me.
(Dream > Game)
– Overall how much did the things/people in the dream/game
look like they would if you had experienced them in waking
reality? (Dream > Game)
– How much did you feel like the events of the dream/game
were happening to you? (Dream > Game)
– How often did you feel "My body was in bed, but my mind was
inside my dream" or "My body was in this room, but my mind
was inside the environment I saw/heard"? (Game > Dream)
Presence in Games and Dreams
7. Gamer Defined
• Play video games on average several times a
week
• Typical playing session more than 1 or 2 hours
• Played 50 or more video games over your
lifetime
• Been playing video games since before grade
three
Type of Game Preferred only considered in latest
studies, seemed to make no difference 5 years ago

10. Lucid – Control Dreams & Gaming
• Subject #014: Lucidity triggered by an event
Michael: Well, once Jean Grey (a marvel comic
and video game character) got loose and started
killing people, I was like this is really weird this is
probably a dream and it was like right after that she
showed up and I told myself that I need to wake
up. I thought that something bad was supposed to
happen and I didn’t want it to happen so I should
wake up.

14. Methodological Refinement
• Previous studies long term retrospective memory
• Collected Dream report and when
• Normal sleep length and rested amount
• Questions on media use history and media used
the day before dream
• Questions reflecting about dream reported
• Dreams (N=152) for analysis were chosen if:
– Last night
– Rested (had typical amount of sleep)

Principal Component Factor Analysis
on Dream, Gamer and Media Use
16. Parallels video gaming/lucidity
• Video game Play
1. video games
technologically
constructed
alternative realities
2. Video gaming has been
associated with
improved spatial skills
3. Low motion sickness
needed to play a lot
4. High absorption is
reported by players
• Lucid/control dreams
1. Dream worlds
biologically constructed
alternative realities
2. Lucid dreamers show
better spatial skills
3. Lucid dreamers have
better vestibular
systems (not susceptible
to motion sickness)
4. Meditation is highly
associated with lucidity
and is training in
developing one pointed
absorption
Self selection?
Yes and No
17. Bottom Line
• Gaming is too wide
spread to reduce to
purely self selection
• There is increasing
social pressure to play
• Gaming is only one
part of our networked
life
Percent growth in US 2006-2007
18. Original Dream Content Analysis
• Hall &Van de Castle Coding System
• Frequency equals intensity
• High inter-rater reliability
• Well developed norms
• Uses categories which are pertinent to waking
concerns that may influence dreaming.
• Those that lead to further research were:
• characters, aggression and misfortune.

27 gamers
56 dreams
male norms
19. Significant Differences
from Male Norms
More dead or imaginary
characters appearing in
dream reports (21% vs
0%).
Why be human in a
game? They have fewer
powers than other types
of creatures.
20. Dead or Imaginary Characters
Subject 001- Dream 11
“I dreamt I was a character is Underworld 2, it was a
werewolf character and then I became a 3rd person. It
was the two main characters, it was the vampire girl
and a hybrid werewolf character and I was another
werewolf character beside them and we went into a
vampire coven and we got to the weapons section of
the vampire coven and then I woke up”
• Later looked at bizarreness due
to this finding
21. Dream Aggression
• Smaller number of
dreams with
aggression (32% vs
47%)
• Yet more intense
aggression (namely
physical aggression,
86% vs 50%) when it
happened
22. Dream Aggression Example
Subject 002- Dream 6
“… I went outside … with my cat and shot these
criminals that were trying to eat my dad and they were
on top of my dad trying to eat his arms and he was
fighting them off, and they were trying to hold him
down and bite his shoulders and there was blood and
stuff. And it was a very graphic shootout for a dream; it
was very blood and guts ya know? And when I ran out
of ammunition there was like pistol whipping and stuff
going on and that one sticks out in my mind because it
was very graphic…”.
23. Dream Misfortunes Fewer
Misfortunes
(7% vs 36%)
Fewer Bodily
Misfortunes
(0% vs 29%)
Thus less victim /more control
Aggression and
misfortune
findings lead to
threat simulation
and nightmare
questions
24. Dream Bizarreness

25. • Domhoff – 2007 meta-
analysis
– dreams are more coherent,
patterned and thoughtful
than previously suggested
– still some bizarreness in
adult dreams
– far less than what was
expected based

• continued practice would allow an individual
to better prepare for these possibly dangerous
instances, were they to arise in the waking
world

Opinion of how video games enter into dreams
• Lucidity, bizarreness, yes.
• Aggression, sometimes.
• nightmares very rare
• 3rd person
“I’ve just noticed that sometimes I’m just there as a hovering
spirit watching things go on and I don’t really have a role … I
don’t even pop up in my dreams, it’s just like I’m watching a
movie … I feel emotion definitely regardless of whether or not
I’m the person involved” – s16
44. Conclusions & Implications
• Lucidity/control
– Do these preliminary results imply that
lucid/control dreaming will become widespread
given the saturation of media?
• Bizarreness
– Are gamers semantic networks more diverse?
• Aggression/Threat Simulation
– Does gaming protect the person against
nightmares?

Hinweis der Redaktion
As just seen in the bizarreness study, in several studies, with increasing methodological sophistication, Lucid/control dreams and gaming have been found to be associated. Here is an example – push audio button
Video gaming is one of the fastest growing entertainment industries with revenues arguably the same as or greater than the movie industry depending on how you count. Therefore gaming is too wide spread to reduce to purely self selection. There is something enticing about being in virtual worlds and there is increasing social pressure to play.
In this factor analysis there are three types of variables: gaming, dream type, and dream bizarreness. Gaming is entered both as history of game play (sum of z-scores of frequency of play, length of play, number of games played and age begun playing) and as day before the dream game play. Dreamers were asked to identify if the dream was lucid, had a third person perspective (observer) and controlablity. Finally subscales from the Revonsuo and Salmivalli scale were entered. It can be seen that gaming was associated with and without lucidity-control but with lucidity-control you have bizarreness. Thus the notion of gaming as mythological re-enactment is supported at a deeply unconscious level.
In order to further delve into the lucidity/gamer relationship let’s now turn our attention to a content analysis of Lucid vs Nonlucid Dreams of Gamers from 4 Previous Studies. We used the Hall & Van de Castle Content Analysis system. While not as many female as male dreams nor as many lucid as nonlucid dreams still there is enough to consider if there are differences WITHIN GAMERS between their lucid and their nonlucid dreams.
Using Schneider and Domhoff’s SAT spreadsheet, we found that lucid dreams for gamers were more aggressive than their nonlucid dreams. The settings were less familiar. There was less self negativity with more general success and dreamer involved success. Finally there was more sexual elements in these gamers dreams.
In short, these are the differences one would expect with lucid-control dreaming, in which lucid dreams deliberately tend toward an overall much more positive dream atmosphere. Although there was no differences in dream types in dream emotions that reached significance.
The one apparent exception is the higher physical aggression in lucid than in non-lucid dreams of gamers. However, given the otherwise positive dream experience, it is likely that the gamers themselves view their often consciously deliberate aggression in these lucid dreams positively, much as they do in gaming.
