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

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 but need not be
![Page 4: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/4.jpg)
• 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
![Page 5: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/5.jpg)
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 in lab before sleep– Gathered dreams for next two weeks– Presence measured after game and after dreams
![Page 6: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/6.jpg)
• 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)

Lucid – Control Dreams & Gaming
• Subject #014: Lucidity triggered by an eventMichael: 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.Gackenbach, et al. (2009)

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)

Parallels video gaming/lucidity
• Video game Play1. 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 dreams1. 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
![Page 18: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/18.jpg)
Is the Lucidity – Video Game Play Association Self Selection?
• Yes– To be a serious player you
need to not suffer motion sickness
– For serious game play spatial skills are an advantage
– Most games of serious players cater to boys
– Those who are able to get absorbed should do better
• No– Almost all children
through to young adults play some form these days
– Spatial skills improve with play
– Girl games are being developed and is a large growing market
– Attention/absorption improve with play
![Page 19: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/19.jpg)
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

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.• Gackenbach, J.I., Matty, I., Kuruvilla, B., Samaha, A. N., Zederayko, A., Olischefski, J.
& Von Stackelberg, H. (2009). Video game play: Waking and dreaming consciousness. S. Krippner (Ed.), Perchance To Dream, Hauppauge, NY: Nova Science Publishers, p. 239-253.

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.
![Page 22: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/22.jpg)
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
![Page 23: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/23.jpg)
Dream Aggression
• Smaller number of dreams with aggression (32% vs 47%)
• Yet more intense aggression (namely physical aggression, 86% vs 50%) when it happened
![Page 24: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/24.jpg)
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…”.
![Page 25: Dreams and video game play games for health conference 2010](https://reader038.fdocuments.net/reader038/viewer/2022110118/55492096b4c90547498b89d0/html5/thumbnails/25.jpg)
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

• 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

Threat Simulation Theory
• dreaming is an adaptive process with an evolutionary foundation (Revonsuo, 2000).
• dreaming allows us to simulate threatening situations in the safety of a virtual environment of dreams.
• continued practice would allow an individual to better prepare for these possibly dangerous instances, were they to arise in the waking world

Participant - Observer Gamer
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

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?
