How do you know if you have a ghost?

Well a ghost is not a dead person, it's a Sprite of a person that wonts to be a human. The way u tell if you have a ghost is if u see things moving in a window that looks like curtins u have a ghost if u have Spiders they are nature so do not I mean not kill them! They show nature and the ghost will become a fairy and not a mimic (a very power full ghost) oh and if u find the ghosts nest if you see any city stuff (made by man) take it out and fill it with leafs,twigs,a turtle stuff like that.
