Purani Pehchan.

Sandhya (Tanuja) suffers from recurring nightmares in which she is stalked by a hideous, deformed witch. Eventually she begins to see the witch even when awake, tormenting her even further. At a party, Sandhya mistakes a beggar for the deformed creature of her dreams. She stabs the woman and is forced into an asylum for the criminally insane where she meets with a tragic death. Mourning their loss, Sandhya’s uncle (Tarun Bose), fiancé (Sanjeev Kumar) and best friend (Bela Bose) begin to see her ghost roaming about. Is it their imagination? Or has Sandhya returned to haunt them?
