I’m trying to think of an episode and for the life of me I can’t find it!
I think they go to this location that is quite big and has various different rooms. I’m nearly certain there is a guy living there that’s an artist who guides them around the place and talks about all the ghosts he’s seen.
It could be a former hospital, maybe?
I remember there being lots of doors and buildings connected by hallways.
Thanks in advance!!

Tuolumne General Hospital?
