Are you afraid of ghosts?

I'm not afraid of ghosts because I never seen any ghost before. However, I have heard and watched stories about ghosts and mysterious things for example monsters and alien, but I never feel interesting in those topic. In the Buddhism, we know that this strange thing is holy and we believe that ghost is spirit. Therefore I will not defy about ghosts or spirits. Finally, I would say that I respect spirit as same as my religion and I can make merit for them so that they can go to the heaven.
