• a person can take control of their dreams narrative
• term was coined by Eeden 1913

Question 2

LaBerge et al 1981

Answer 2

verified lucid dreaming through volitional communication

Question 3

PFC and lucid dreams

Answer 3

PFC - involved in lucid dreaming and metacognition

Question 4

Stumbrys 2013

Answer 4

studied PFC invovlement in lucid dreaming using tDCS

Question 5

tDCS

Answer 5

transcranial direct current stimulation, used to manipulate the activation of the DLPFC

Question 6

Stumbrys 2013 results

Answer 6

according to the participants self ratings, tDCS over the DLPFC during REm sleep increased lucidity in dreams

Question 7

Filevich 2015

Answer 7

explored metacogntive mechanisms in lucid dreaming

Question 8

Filevich 2015 results

Answer 8

showed shared neural systems between lucid dreaming and meta-cognitive function, in particular in the domain of thought monitoring

Question 9

narcolepsy

Answer 9

sleep disorder with high propensity for lucid dreaming

Question 10

Dodet 2015

Answer 10

found that narcoleptics have a high propensity for lucid dreaming without differing in REM sleep characteristics from people without narcolepsy

Question 11

Blagrove and Hartnell 2000

Answer 11

lucid dreaming is associated with trait creativity, need for cognition and internal lOC

Question 12

lucid nightmares

Answer 12

occurrence of distressing dreams despite being aware in a dream

Question 13

lucid dream fragility

Answer 13

• rareness of lucid dreams due to fragile meta-cognition
• may also be rare due to personality

Question 14

Konkoly 2021

Answer 14

illustrates how experimenters can question lucid dreamers during ongoing dreams and ask whether the more extended two-way communication during lucid REM sleep dreaming is feasible

Question 15

Konkoly 2021 - study that was published in current biology

Answer 15

• scientists gave the dreamers math problems
• one sleeping Ps responded correctly by moving eyes the amount of times
• there was 36 dreamers
• over 158 attempts
• responded correctly a 5th of the time
• only wrong 3% of the time

Question 16

Konkoly study and lucid dreamers

Answer 16

• looked at normal sleepers, people already good at LD and NON-LD that they tried to train to LD
• tried 379 times to get non-LD to answer math problem
• only had 1 correct
• over 360 no response
• so, lucid dreaming is key to dream communication
