Dear Bizi,

The ghosts think that you have given them the living room.
To convince them otherwise, you have to open the doors completely and leave them open. Let the cats have full run of the place.

Who cares about the furniture?? (Are your serious??) The ghosts will move on after you tell them that they need to leave now.

You say, "Get out of the house and stay out."
This will work.
