Lavender town syndrome is so far the only one that caused sucide (even though the sucide weren't real). What about clestics tower, the burial ground of gen 5? Just think about it, burial ground, I just THINK that buried alive is not at one tower, but 3 tower and a moutain (mt.pyre of course). Ghost, possibly, but I think that buried alive, is the real horror of all of the burial ground of pokemon
