Do Ghosts Haunt People or Places?

Ghosts can "haunt" (or be attached to) either. In the case of "stone tape" the phenomena is obviously associated with a place. But ghosts may also attach to individuals, which means that it isn't always possible to escape ghostly activity just by moving house.
In the most extreme cases a lost Spirit may attempt to take over the body of a living being. Such cases of possession are thankfully rare, but might account for a proportion of cases diagnosed as mental illness.
