I saw an article the other day saying "this house is haunted by several ghosts" and I have questions

Do these ghosts have a rota for their appearances?

If not then what happens when two ghosts appear at the same time? Do they scare each other?

This could be awfully chaotic

..a ghost appearing clanking chains, then another one appearing and shouting "Oi those are mine" and them scuffling over it

..a ghost wandering about with the wrong head under his arm

it needs sorting out
