When Imgur user Ashontez got a new technical support job in October and began working graveyard shifts, he knew it would take time to adjust to his new sleeping schedule.

He was set to work from 1 a.m. to 12 p.m., so he had a difficult time getting used to going to bed in the afternoon and waking up around midnight. What he wasn’t’ expecting, however, was a creepy stranger making himself at home in his apartment while he was at work.

Not long after starting the job, Ashontez began noticing things that were out of place when he came home or after he woke up. Lights had been left on, doors were unlocked, and food went missing from his refrigerator.

He chalked it up to either not remembering doing these things himself or his cats getting into trouble at first, but it kept happening even when they weren’t there anymore.

Things got much worse in December when he saw a $3,000 charge on his credit card account. He had no idea how this could have happened, because he always had the card with him. As he was working from home around 3 a.m. that night, he heard someone trying to unlock his door. Luckily, whoever it was couldn’t get in because the deadbolt was engaged and ran off. He changed the locks shortly after and notified the police, but they didn’t find anything.

Everything came to a head when he decided it was time to pull out the Christmas tree and decorations from his storage closet and set them up.
