I have also heard weird stories during my childhood. In villages slapping of people by “ghosts” around midnight was a common story. There will be a knock at the door, the face and head of the “visitor” would be totally covered with a bedsheet and the voice would be familiar.
“Come, come..,” the "ghost" would invite the people in deep slumber. The victim would follow innocently and once they reach an open field, the victim (he/she) would receive a tightttt slap and fall unconscious.
There was another one well-known category called “Ammukuvan” (What’s the translation? OK, one who presses hard) in Tamil. When some one sleeps in open terrace, this Ammukuvan would press his/her stomach so hard that the person would find it difficult to breathe. I used to be terrified but my communist brother took it as a challenge and slept many times in open terrace.
Well, stories are stories. Let’s not analyse deep. Do not forget those days there were no mobile phones (to contact the family if Amukuvan strikes or ring up police if “ghosts” slap).
Say cheese 24/7. “Ghosts” will also smile at you, shake hands with you and bid adieu.
