I have a big backyard, slightly smaller than an acre, but i have no trees. Its basically all grass with a small rainbow playground in a corner. Would Ghosts in the Graveyard still be fun even if there aren’t a lot of hiding places?

It is said that some ghosts chase you if you get close(in order to see the ghosts from a closer distance) to a place where they use to appear at night.
If you let them come to you, Can they do you any harm?
