I've heard of this Ouija board through a friend of my sister's, PJ ji!
Unfortunately in their family (which practiced this Ouija thing for a very long time), this friend of my sister's had her younger sister die of Cancer at the young age of 19! And a younger brother got married at 18 (intercaste love marriage), ditched his studies and god knows what he is doing now!
For some strange reason, I have associated the Ouija board practice with this death and disaster!
