During dreams, bizarre scenes you encounter can seem as tangible as reality; you feel as though you're really flying through the sky or being chased through a jungle of bright-purple trees. But in special cases, people realize they're in the midst of a dream as it's unfolding.

Called lucid dreaming, this phenomenon occurs when we suddenly regain our capacity for metacognition, or thinking about our own thoughts, in the middle of a dream. Lucid dreamers can sometimes even control the content or trajectory of their dreams. Now, researchers claim that they've found a way to "train" people to lucid dream by having them meditate and complete virtual-reality-augmented exercises while they're awake.

In a study involving a few dozen participants, the scientists found that repeating this training twice a week for a month significantly increased how often participants experienced lucid dreaming. They say the approach could have practical applications as an intervention for people with nightmares, anxiety or post-traumatic stress disorder — but those applications are theoretical, for now.
