i have heard in my country. never to cross a bridge built above an open sewage after 12 am
as the ghost catches u...... n makes a home in ur body.......
one day my uncle was too late and he had to reach home as quickly as he can so he took a short cut and when he was cross the bridge above d gutter he was caught by a ghost or spirit or maybe demon..... when he reached home he started behaving weird..... so his mom means my grandmom...
took rice n red chilly n salt n something more.... n she took those ingridents in her hand and created a circle clockwise around his body ........
n den put it on a heated pan ..... it created smoke n crackin n poppin sound n den threw it in d dustbin.....
and after dat he become absolutely fine....
