Guy thinks landlord was leaving strange notes in his home — what he found out was even more disturbing

The feeling of being watched is extremely creepy and the idea of someone secretly sneaking into their house can leave anyone disturbed. For one Reddit user, this unsettling fear became a reality, but the reality was something no one could imagine. On May 2, 2015, r/legaladvice turned to Reddit to share a bizarre experience. He revealed that mysterious post-it notes had been appearing in his apartment. The first one showed up on April 15, and from that moment on, the mystery only deepened.

The person wrote, "I found a yellow post-it note in a handwriting that wasn't mine on my desk reminding me of some errands I had to do, but told literally nobody about. While odd, I chalked it up to something I did in my sleep, thinking maybe in my half-awake state I scrawled it so it didn't appear to be my handwriting. I threw it out and thought little of it." He discovered another note, this time on the back of his desk chair, on April 19. The handwriting was the same, but this time the note cautioned him about saving his documents. There were no indications of a break-in, but he was still frightened. So, he set up a webcam facing his desk, using a security app to start recording whenever it detected movement.
On April 28, he woke up to discover yet another post-it note. This one said, "Our landlord isn't letting me talk to you, but it's important we do." Curious and uneasy, he rushed to check the webcam footage but found nothing at all. The folder was empty and his computer’s recycling bin had been emptied as well, while he was certain he hadn’t done it. This indicated that someone had noticed the camera and erased the evidence. Furthermore, on May 1, the mystery deepened. Another post-it note appeared, this time outside his door but completely blank. Similar empty notes in different colors were also scattered throughout the apartment complex.


The Reddit user added, "Do I have any legal recourse here? I have no proof except for the Post-its, but those are written by my pen and on my Post-it notes, so conceivably I could have faked them. Would contacting the police get me into any trouble, if they can't determine an outside source for this?" Digging through old papers, he stumbled upon a letter from his landlord and found that the handwriting was an exact match. Very soon, the theory that the landlord was sneaking into his home started spreading in the comments, alongside plenty of other guesses. However, about nine hours later, he posted an update claiming that carbon monoxide had been the unseen force behind the entire mystery.
The person set up a carbon monoxide detector in his bedroom, and it read 100 ppm. It turns out that prolonged exposure to the gas can cause issues with the brain such as memory problems and unconsciousness. This revealed that the person writing the notes wasn’t anyone else but the user himself. The carbon monoxide was causing memory loss, making it harder for him to remember things. He wrote, "Thanks to everyone who sent suggestions and gave advice on how to proceed– especially to those who recommended a CO detector... because when I plugged one in in the bedroom, it read at 100ppm."
