Homeowner finds chilling note with terrifying warning left by previous owner after moving into new house

A homeowner has shared a chilling note they received from the previous owner of the new house they've just moved into.

It's not exactly uncommon to leave something nice, whether it be glass of fizz or even some chocolate for those moving into the house you've just sold.

But to move into a new home and find a terrifying note instead of a bottle of wine is the last thing you want to find during the exciting time of moving into new digs.

"Found this note taped under a panel in this storage cabinet, previous owner just trolling me?" the anonymous Reddit user wrote in a now viral post.

One side of the note reads 'Don't look under the floor', while the other side has a 14-digit code.

Yep, not what you want to see (Reddit/issaquahhighlands)

The Reddit user posted a snap of the note to the popular social media platform in the hope of getting some possible explanations, and the new homeowner certainly wasn't short of them.

"14 digits... coordinates? Safety deposit box? Hidden safe combination? Alphabet coordination to each number?" one Redditor asked.

Meanwhile, a second provided their own detailed theory with: "This is unique.

"Toronto Library card numbers used to start with 290 and were 14 digits long (just as long as your number) in the 90s. They’ve since updated their card numbers."

The comment went on: "I know this because I have a knack for memorizing strings of numbers. Pi is 3.14159265358979.

"My username is in fact the prefix of my old Toronto Public library card. Notice how it also starts with 290.

"I think under the cabinet are old library books, associated to a library card from the 90s Toronto Public Library card system, that you have a note listing."

While a third remarked: "So, from experience, someone is trolling.

"I used to work in this office of about 8 people (including me) but 7 worked in the field and only came one day bi-weekly.

"I used to leave little notes like this all over the place, just for kicks. I was young and dumb at the time."

And a fourth penned: "Trolling. Because in his mind it is funny to watch you tear out the floor.

"Don't worry about it. If it really bothers you, you can knock on the floor, and if anywhere sounds different than most of the floor or where the joists are, then you can waste your time."
