Ouija Boards

Because of being raised in an extremely conservative Christian home I was always taught to stay far away from ouija boards. (You know, Satan and all). I'm no long afraid of "opening that door" but I've also never once heard of a positive story coming from their use. It's always dramatic and honestly a little silly seeming. So, has anyone used one and just had a normal experience? As of late, we've been having lights switching on and off in the house, so I figured using a ouija board might be a good way to contact the light flicker-er. Thanks!
