Does Filch ever clearly see or hear a ghost?

Question

I have always had the impression that Squibs in Harry Potter cannot be distinguished from Muggles in any way but their parentage. If you know of convincing evidence otherwise, please post it as an answer to the following question: Is there any way to tell a difference between a Squib and a Muggle? So far, I am most convinced by vap78’s “no” answer.

Anyway, I’m asking this question as a followup to one of the posts there. Apparently Pottermore says, or said, that witches and wizards find it easier to see and hear ghosts than Muggles (CandiedMango’s answer).

Are there any examples in the books of Filch interacting with a ghost in a way that implies he can clearly hear or see it? Note that Peeves the poltergeist does not count as a ghost.

Answer 1

Not that I can find

I searched my copies of the books (including Harry Potter and the Cursed Child) for all (several hundred) instances of Filch’s name, and I couldn’t find any unambiguous instance of Filch perceiving a ghost. There’s ample evidence that he can interact with Peeves (obviously), but he doesn’t seem to have carried on a conversation with any other ghosts, or otherwise reacted to their presence, at least as recorded in the books.

In light of J.K. Rowling’s statements about Squibs being unable to see Dementors, as well as her statement that Muggles cannot clearly perceive ghosts, and her assertion that a Squib is a “non-magical person born to at least one magical parent,” it does seem likely that Filch could not have clearly perceived the ghosts (with Peeves, of course, being quite a different sort of entity). That said, the evidence on Pottermore merely states that Muggles “might only feel that a haunted place is cold or ‘creepy’”, without asserting that this is all that a Muggle could ever perceive, and states only that a Muggle could not see a ghost in “perfect focus.” As such, it is entirely possible that Filch (even if essentially non-magical) could perceive the ghosts blurrily, or hear their speech fuzzily.

Answer 2

It's not clear.

Like Adamant, I couldn't find a clear-cut incident of Filch interacting with a ghost. However, Filch did find himself in the same vicinity as a ghost on at least one occasion. In Chamber of Secrets Filch interrupts Harry when he's having a conversation with Nearly-Headless Nick:

“You’d better get out of here, Harry,” said Nick quickly. “Filch isn’t in a good mood - he’s got the flu and some third years accidentally plastered frog brains all over the ceiling in dungeon five. He’s been cleaning all morning, and if he sees you dripping mud all over the place-”
“Right,” said Harry, backing away from the accusing stare of Mrs. Norris, but not quickly enough. Drawn to the spot by the mysterious power that seemed to connect him with his foul cat, Argus Filch burst suddenly through a tapestry to Harry’s right, wheezing and looking wildly about for the rule-breaker. There was a thick tartan scarf bound around his head, and his nose was unusually purple.
“Filth!” he shouted, his jowls aquiver, his eyes popping alarmingly as he pointed at the muddy puddle that had dripped from Harry’s Quidditch robes. “Mess and muck everywhere! I’ve had enough of it, I tell you! Follow me, Potter!”
So Harry waved a gloomy good-bye to Nearly Headless Nick and followed Filch back downstairs, doubling the number of muddy footprints on the floor.
_{(Chamber of Secrets, Chapter 8, The Deathday Party).}

Did Filch ignore Nick because he was so focused on the muddy footprints on the floor and overcome with ire towards Harry? Or did he ignore him because he couldn't see him? It's open to interpretation either way. This is the most relevant passage for making a decision, though.
