Emraan Hashmi spent six sleepless nights at a bungalow in Shimla imaging the worst when he went to shoot for his film Raaz 2.  He mentions that he is drawn to horror - to films, stories, incidents and of course, places that exhibit the potential for it. His team and he were put up at the former Viceregal Lodge there, which is now the Institute for Advanced Studies. A huge white Victorian castle, right out of Transylvania as it were, with curtain creepers covering the walls as though the stories they otherwise told were meant to be kept under wraps.
