Bipasha Basu, whose forthcoming film "Raaz 3" deals with black magic, says one of her friends had once become a victim in real life.
"Every day was a struggle for her. She was emotionally drained, exhausted and disturbed. Reliving this for 'Fear Files', memories of those days came flooding to my mind and still manage to send a chill down my spine," Bipasha said in a statement.
"Fear Files" brings on screen real supernatural incidents that have occurred in India.
Bipasha, who is on a promotional spree for horror flick "Raaz 3", will narrate a video diary for Sunday's episode, which revolves around a fashion designer named Anahita. The actress shot this sequence recently in Mehboob studios in Bandra here.
She also shot a cameo for thriller show "C.I.D.".
