"Induction of self awareness in dreams through frontal low current stimulation of gamma activity"
Don't know if anyone else has seen this, just announced today, but I think it's going to change Lucid Dreaming completely:
Lucid dreaming can be induced by electric scalp stimulation, study finds | Life and style | The Guardian
Basically says that low current electrical currents within the 20 to 40 Hz range produce lucid dreams in people that had never before had lucid dreams, or even knew about them, 70% of the time.
I think this is pretty big.
