I grew up a spiritual Brazilian where we have our own version of voodoo (macumba). http://en.wikipedia.org/wiki/Macumba and live in Florida where we have Santeria. I knew someone who practiced Santeria.
Fortunately, I grew out of believing childish fairy tales and horror stories regarding witchcraft and sorcery. If you're mentally ill or immature in the mind, I can see you holding onto those beliefs as facts. It probably means you were raised in fear of such things and don't understand concepts such as confirmation bias.
So the person that you "knew" practiced Santeria was practicing fairly tales?
I don't fear evil spirits but I know they exist. I have come into contact with them and then there are others that outwardly try to contact them themselves. But again I don't expect you to believe anything spiritual
