Actually, people are more likely to be scared of "ghosts" if they live in an old or ancient but large house. Thank god, my house is modern and does not have any "mysteries". So, I've never been scared of ghosts in my house.
But when I go to our hometown village, they are like kampongs. They scare me a little. Someone told me, Ghosts breed in the bathroom. I'm afraid it might be true there. My grandma sometimes tells me stories about ghosts. So, a little scary that is. But no big issue for me now though.
