Are ghosts real, asks the title? But what does "real" actually mean anyway?

Spirits are not ghosts, ghosts are not spirits. Defining what a ghost actually is, however, is somewhat harder than saying what it isn't. Think of things this way, perhaps? A spirit is able to animate a body but a ghost has no such power of animation.

edit: This morning I was reflecting further on this topic and another thought came to me. It's not possible to interact/communicate with a ghost.
