>The sweet spot was 40 Hertz. Zapping sleeping volunteers at this frequency, part of the so-called gamma wave band, led their brains to produce brain waves of the same frequency, the researchers found, which triggered lucidity 77 percent of the time, as determined by self-reports from the dreamers after they were awoken.
>Now if we look to see the scores they gave for how much dream insight, dissociation and control they had, we find that the averages for the gamma stimulation condition are around 0.6, 1.3, and 0.5 respectively.
I don't understand. A score of 0.6 for insight means, at best, 40% strongly disagreed that they knew they were dreaming and 60% perhaps moderately disagreed (score=1). Some higher scores for the successes would result in even more than 40% strongly disagreeing that they knew they were awake. I could see it having an effect for a small number of people, but how does that translate into "triggered lucidity 77 percent of the time."
