My mother rented (almost free) a palace like haunted house in a small town called Churu in India when I was a child, 40 years ago.
She did so because she earned very little to be able to pay rent and owner of the haunted palace wanted somebody to live in the house so it can be taken care off. Whenever we ran out of money towards the end of the month someone in the family would find little money in the toilet which was enough to buy food. Therefore we never complained and always blessed the souls in the house.
My mother always asked us to study very hard otherwise souls would be very angry with us. So all my brother and sisters including me studied very hard because of fear of unseen ghosts and now all of us have very good jobs and successful careers. Therefore I love ghosts even though I have not seen one in my life yet!
