<human>: Can you condense the text into a few key points?

(Throwaway account, i dont want him knowing im telling anyone about this)

So my dad is a pretty superstitious guy, he's convinced his house is haunted. Repeatedly over the past six years he has gotten people in to cleanse the place because he has had "Sightings" of someone else closing doors and such other nonsense. The house was owned previously by a young couple who moved out not two weeks after buying the place without giving a reason (Real cliche right? My dad found this out by contacting them but they wouldnt give a reason, although they did say the place just felt wrong)

Anyway i came home from college with a load of washing. My dad and mom are separated, so they live in different houses. In my bag i noticed that i had d brought a steak knife that was, coincidently, the same make as the one my dad owns. I stuck it in the knife holder and made a mental note that i would bring it back with me when i left. (I dont know why i had a steak knife in my bag, i think i was using it to open cans of tuna or something)

Fast forward a week and MY DAD IS SELLING THE HOUSE. Apparently that knife has been missing for years and it just turning up out of nowhere freaked the shit out of him so he ran right to the auctioneer and put the place up for sale. Now i tried to explain it to him, i tried believe me but he thinks im just making it up. I really dont know what to do, he's fucking crazy when it comes to things like this. My Mom is going apeshit and my brother is basically laughing his ass off at the whole thing.

The worst thing is that knife was bought as part of a set, made and model and all so it looks exactly like the others. He thinks some ghostly asshole came in and put the knife there as a kind of "Get out" Suggestion.
<bot>: I replaced a knife that looks exactly like a knife my dad lost years and now he thinks the house is haunted. He's selling the house
