I'm a big believer in the supernatural, but alas, never used one. I'd rather experience it with someone than by myself; I have no idea why...
a guy our family has known for ages used a quija(sp?) board when he was 26, and now hes 30 he has had white hair since using that quija board, it either scared him that much or something else, but just makes u wonder...
They work if you actually believe they will work...at least, when I used one it f**ing worked, to some extent. If you heavily believe in the supernatural the chances of something happening are far greated. :>
