Specifically in season 4's "Elegy" (which was a significantly better episode than this). Not only that, it was one of the very few times where Scully 100% could not deny what she saw. She was even disturbed enough by it to discuss it with her therapist.
This is all forgotten in this episode. It'd be one thing if Scully repressed the events of that episode and Mulder reminded her of it, but instead you get the sense that the writers can't be bothered with keeping up with the continuity of the show. "How the Ghosts Stole Christmas" was written by the showrunner, which is even more damning.
As for the rest of the episode, it's rather lackluster. It obviously didn't have much of a budget considering we only get to see one room of the mansion and a few hallways. And on top of that, there are those annoying psychobabble-spouting ghosts. Meh.
