According to their eBay listing, it all started when one of them saw that the building's landlord had put the old hallway mirror out on the lawn as rubbish. So, being resourceful, he retrieved it, added some silver paint and leaned it up against their wall above the radiator.
Soon after that, things supposedly got weird.
"We both experienced what I can only describe as intense sharp stabbing pains," the sellers wrote to prospective buyers. "They would strike us both at the same time."
The two flatmates also complained of waking up completely drained of energy, screaming in the early morning hours with horrible feelings of impending doom.
Though, to be fair, that kind of sounds like my typical weekday. Only with fewer tears and significantly less self-doubt.
Regardless, this is the point where one of them should have turned to the other and asked, "How about we just ... throw it away?"
But, that would be too logical. And, besides, the sudden emergence of blood was sort of interesting and new.
You see, in addition to growing increasingly sick and depressed from all the evil hauntings, one of the flatmates even claims to have woken up with deep body scratches, for which he blamed the mirror and kindly provided a link on eBay for photographic proof.
It's also entirely possible that he just has a pet cat. Or, perhaps, an amazing lover. Or both. (But not like that.)
