That is what I see in movies and from what I saw in the past. Perhaps, we cannot believe that because, in our place, that way didn't exist, but in the other places, that way is existing.
That's right dude, maybe people here mostly don't believe it but in my area like that it's normal. If they laugh because they don't believe in spiritual things like that, then I will laugh at them because they don't believe. Voodoo is real and they must believe, I myself did not believe in mystical things like that but after I saw it many times I believed it. Maybe their place is too modern so they are not yet familiar with the occult.
