To paraphrase realtors since time immemorial: Context, context, context. It can be one of Egon's experiments they find while going through his hidden lab. It can be a deliberate experiment of Paul Rudd's to see if he can "haunt" Mr. Stay-Puft. It can be an accidental possession when he misuses some piece of Egon's equipment. It can be one of the first -- tiny -- signs of something waking up in the Shandor mine. It can be a daydream Rudd has while sitting in his classroom after the ghost trap the kids bring in reminds him of what went down in New York so many years ago. I can keep spinning different contexts for that scene, some of which work organically and are cool, some of which are ridiculous and cringe. Since we have zero indication of when this is in the film, what's going on around it, what causes it, where things go from where we're left... I think it is absurdly premature to cry foul at this point.
