I went through a phase of using a Quija board lots with friends (who hasn't?)
We made friends with a spirit girl named Hilary, who'd died when she was 9 years old. We used to just chat to her and she'd tell us stories, and generally acted really pleasant and friendly towards us.
It was good fun until the "spirit" girl, Hilary, started threatening us. Being young, naive kids, we were really amused, excited
and scared, in equal doses.
A female friend of mine got so into using the Quija board that she started using it alone. She then became convinced she was involved in some "battle of the spirits", that was going to take place in the near future. She became so unhinged by this that the only thing that eventually brought her out of it was being
exorcised.
