In an Asian country, they come to the graveyard, sleep in that place, and hoping that they will dream about the number of the lottery that will be out. And if they dream about the number, they will buy the number with some money.
A few years ago, some of my friends were asking me what number that will come out in the lottery game. As I don't know anything, I give a random number which 2 number and suddenly, tomorrow, that number comes out and my friends are the person who can win some big money.
I think that is not voodoo, but perhaps, that is what people used to win the lottery.
Asians still believe in mystical things in gambling, but there are indeed some people who get results from it. the thing that I think is too scary is to sleep on a graveyard to get a lottery number. even strange things like asking lottery numbers to people who are considered weird "like crazy" when that person mentions a number then they will use that number on the lottery.
