Bhool Bhulaiyaa (2007) is a psychological horror-comedy film directed by Priyadarshan. The story follows Siddharth (Shiney Ahuja) and his wife Avni (Vidya Balan), who return to India and move into their ancestral palace, despite warnings about supernatural occurrences. Strange events begin unfolding, leading Siddharth to call his friend, psychiatrist Dr. Aditya Shrivastav (Akshay Kumar), to investigate. As the mystery deepens, Aditya discovers that Avni might be possessed by the spirit of Manjulika, a vengeful dancer from the past.

Blending humor with suspense, the film keeps the audience engaged as Aditya unravels the truth. The climax reveals that Avni, suffering from dissociative identity disorder, had unknowingly adopted Manjulika’s persona due to past trauma. The film masterfully balances psychological depth with entertainment, making it a cult classic in Indian cinema. Vidya Balan’s stellar performance, coupled with Akshay Kumar’s comic timing, made Bhool Bhulaiyaa a memorable and widely appreciated film.
