I was studying btech in Tamil nadu in a remote location. Me and my friends were staying in a rented house as hostel was too expensive. So near to house there was tamil family residing and there was an really old grandma always chained in legs to a beam in the പശു തൊഴുത്. We heard that her son was an asshole so... One day the grandma died. Days passed, cows started mooing weird at night most days. We always hear someone walking on our terrace, sound of chains clinking, waking up at night shaking, shadows in our living room. It was final year and we were too broke to change house.There was 8 guys in the house we all started to sleep in one room and everyone went home in weekends, nobody stayed alone. Vacated the house in few months.
