I had not considered the term "redirected".

I imagine so. I mean if a black tenebrous entity descends upon me in a location haunted or entered my home by another's foolish mistake I can send it away to the world or to where it belongs and cannot return from.

And just as a 'ghost or spirit' can drain a battery, so can they be drained. But that is something reserved for the truly deserving of it nasties.
