Electric scalp stimulation may help control nightmares, especially among those who suffer from post traumatic stress disorder, a new study found.
According to the researchers, stimulation can allow recognizing and controlling the dreams, which is a state of lucid dreaming.
The scientists also found that applying appropriate amount of electric currents to a person's scalp, the sleeper can help manipulate their dream's plot and control their behaviour within the dream, the Guardian reported.
Professor J Allan Hobson, from Harvard Medical School said that it is amazing to see that scalp stimulation can influence the brain in such a way that the sleeper or the dreamer becomes aware that they are dreaming and can direct them according to their wishes.
Hobson further explained that the study can play a vital role in psychiatric research and he would be careful while interpreting the results because it can have direct significance in the treatment of medical illnesses, but it is definitely a step forward in understanding how the brain manages to hallucinate.
