The *famous* game of Charlie Charlie?
Never heard of it.
Those who play with ouija boards, or any other kind of occult activity, are asking for trouble.
Strongly agree.
Even just joking, having fun, fooling around with the occult, pretending to do a seance, play-acting devotion to an evil entity, puts you at extreme risk.
A bodiless entity can't overpower you unless you let it: but "letting it" can be something as stupid as wearing an occult emblem on a T-shirt.
Just wait the movie about Charlie, Clarlie will be released in the next 6 weeks.....
Supposedly the so called spirits end up harassing the one invoking them to the point of suicide, because the whole goal is that of a bait to get the spiritist to join them in hell.
