You can have whatever belief you want, but don't discount other's experiences. After my sister's house experience, you can't tell me there's no such things as ghosts. Hearing something walk up and down the steps when no one actually is, hearing toe curling screams in the same room where you are eating, seeing people that you know aren't there, having something touch you while you're watching TV, have things move that you know you haven't touched. These things happend to my family. You can keep believing whatever you want. Your reality is what you perceive.
