Nighttime dreams in which you show up at work naked, encounter an ax-wielding psychopath or experience other tribulations may become a thing of the past thanks to a discovery reported on Sunday.
Applying electrical currents to the brain, according to a study published online in Nature Neuroscience, induces "lucid dreaming," in which the dreamer is aware that he is dreaming and can often gain control of the ongoing plot.
The technique might help people suffering from post-traumatic stress disorder, who often have terrifying dreams in which they re-play the traumatic experience.
"By learning how to control the dream and distance oneself from the dream," Voss said, PTSD patients could reduce the emotional impact and begin to recover.
But Voss does not foresee a commercial market in lucid-dreaming machines in the near future.
