You don't need a teacher, a teacher can only pass on there point of view and, essentially there 'Path'. You're meant to find your own path. The information you want isn't that hard to find. Check you local library (I know people say that, but i live in a very small religious town, and i found a book or two) If you think it might seem weird, ask for books on astrologically or ghosts and the books might be around there. The internet is another option for information, although it can be unreliable, i am not saying all books are fact, but more reliable than random internet pages.
