According to a study published in the 'Journal of Neuroscience' in January, people who have lucid dreams have different brains than those who don't. Lucid dreamers have a higher volume of gray matter and activity in the part of the brain responsible for strategy, memory recall and other cognitive tasks. To read Peter Maich's account of his years of lucid dreaming is a look inside the mind of someone who apparently experiences some serious prefrontal cortex action. Some dream experts believe that this capacity can be developed and that anyone can control their dreams. Recently, there's been some positive results in sleep labs using lucid dreaming to treat anxiety. At the same time, Maich's dreams sound exhausting and intense. If you could overcome your fears through lucid dreaming, would you try to learn how?
