answer: it’s up to you!
explanation: believe what you want to believe unless that belief is damaging to someone/the environment.though, there’s no science to support the existence of ghosts. sometimes believing in a spirit such as a ghost can provide some comfort to ones self as they believe that their relatives are always watching over them and protecting them. yet believing in such spirits can make one feel paranoid as they believe someone is always watching and no matter how alone you feel there’s always someone there just watching, unable to interact.
