The only thing I know is that voodoo is not good witchcraft, I actually think it is classed under black magic. Very dangerous stuff. I believe in both (white and black magic) and black magic is one thing that I would never get involved with.

See if you can get in touch with a medium, maybe they could help you with the voices and the things you hear. You could have had a curse put on you and that needs to be lifted. I don't mean to scare you, but these are all possibilities.

It could all be innocent as well, try remembering your dreams and invest in some good dream books. Not all "bad" dreams necessarily mean bad things.

Good luck
