Senoi

The Senoi are a Malaysian hunting and gathering people who were reported to make extensive use of lucid dreaming to ensure happiness and mental health. This people lived in the mountains of Malaysia and had a society free of crime and mental illness. In the morning the entire family, discussed their dreams. This practice lead to a kind of positive dreaming. When they became teen-agers the Senoi did not have nightmares anymore. All their dreams were positive. They achieved this by means of a very original system. That the Senoi did not suffer of neurosis or psychoses sounds unbelievable. But it is well researched and the results confirm this. The way they handle their dreams seems to be the key to this.

The rules that the Senoi had when it came to their dreams were the following:
If there is danger in your dream, you should confront and conquer it. When for instance a child had dreamed that a tiger attacked him, his parents would tell him that such dream-tigers could not hurt him. They encouraged him to attack the tiger himself the next time. And if he wasn't strong enough, he could call a 'dream-friend' to help him.
