Imagine coming home after a long days work to discover your door unlocked. This alone doesn't cause for immediate panic because often it's hard to remember if you even locked it that morning. As you warily enter the house, you are relieved to see your TV is still on the wall, and the computer is still sitting on your desk. When you take another step in, however, you start to feel this uneasy feeling, like someone had been in your house while you were gone.

You notice a smell of cleaning products in the air that you don't remember being there that morning, and to your shock, you see the bedroom door you always leave open, closed. Now is the time to panic. You search the house, calling out for the perpetrator to show themselves. Your children's rooms are immaculate: vacuumed, with clothes folded and beds made, and toilets scrubbed.

Someone has definitely been in your home for hours, pillaging through your intimate belongings, only they hadn't taken anything. The only thing they leave behind is eerie toilet paper origami roses, a staple of the US prison system.

Although this sounds like a funny sketch from a comedy show, this actually happened to Massachusetts man Nate Roman this May. Roman says in an interview with New York Post: "Growing up in the age we do, my first thought was a serial killer. My next thought was wondering if my son was safe, worrying if someone was still in the house."

Despite the ridiculousness of the crime, it is still a crime. The act of intruding upon someones home not to steal, but to acquaint oneself with the environment is almost creepier than a robbery. Just the thought of someone possibly getting off by touching your objects and lounging in your furniture is extremely off-putting.

The motive of this cleaning criminal is still unknown and he or she is at large. It's speculated it may have been a mistaken house tidied by a cleaning crew--but that seems less likely than a creep having a go in a home with an unlocked door.

Don't forget to lock your doors at night and when you leave in the morning and watch out for toilet paper roses.
