The description for The Other Side has always made me think of this episode, so since it got posted officially to YouTube I thought I'd share. Spirits trapped in a realm to never be released until Judgement Day?
Ray: I wonder why they call it the Place of Lost Souls? Winston: Yeah, I was wondering the same thing. Aren't they all ghosts? Egon: Well, maybe this is where the worst ghosts of the lot get stuck because they're too awful for anyone to see?
From the way it's worded to the way it's portrayed in the episode, I've honestly wondered if they didn't take some inspiration from it when coming up with the back story.
Wow, talk about ghost trains; this episode was littered with them! (PSA: this is the first time I've ever watched a full episode of The Real Ghostbusters lol)
