"I love watching horror films because I don't get scared easily. So for me it was like, 'Arey, kaise karungi ye main (How will I do it!)... when I don't get scared, how am I going to act that I am scared, I can't do it'," the 26-year-old said here.
But the model-turned-actress gives full marks to her director, Vikram Bhatt for guiding her the right way.
"I don't think any one could have made me do what Vikram (Bhatt) has made me do. The whole imagination and expressions... I think the whole credit goes to the director," Esha said.
"Raaz 3" revolves around black magic, but Esha doesn't believe in the concept.
"I don't believe in black magic. But, I mean its never happened to anyone around me or to me, touchwood. I just think if there is good, there is (also) bad," she said.
"Raaz 3", set to hit screens Sep 7, also features Emraan Hashmi and Bipasha Basu.
