Researchers at the University of Frankfurt have discovered a way to induce ‘lucid’ dreaming, a form of dreaming between REM and being awake, in which the subject has conscious awareness of controlling the outcome of their dreams. Test subjects that were stimulated with a 25-40hz frequency in a technique called Transcranial Alternating Current Stimulation (tACS) were reported to have increased ability to control and change the actions of their dreams at will! http://news.yahoo.com/electrical-stimulation-brain-alters-dreams-213113849.html
