I try to dodge the ghosts whenever I can. It's nothing personal, but they raise too many questions with no right answers. I always have to be on guard for them; there are some spaces I'm certain they never inhabit, and there are some places where I won't go anymore whenever possible. It takes a lot of work and strain to always rejig travel arrangements to minimize run-ins, probably more than it's worth.
The encounters aren't so bad, but the lingering haunting is the rough part.
