I personally believe in ghosts, as they are spirits trying to make themselves known. Whether it be a good spirit or a bad one I believe they exist. I watch the show "Ghost Hunters" on the Sci Fi channel and they've found some creepy things, enough to make me believe. Also, onto the witches area... Witches are considered anything that worships satan, or casting black magic. Not black magic as in a joke, "oh that black guy knows how to disappear with other people's things." Black magic which has been practiced over the generations, which I believe it opens portals which allows evil spirits to come through the spiritual realms, thus leading to exorcisms. That's what I believe, please don't flame my beliefs.
