Some people have great roommate experiences, but for others, living with the wrong person can feel like a nightmare. One person shared how their cheerful roommate vanished without a trace. Five years later, while cleaning the room to sell the house, they discovered a hidden hole in the wall filled with notes urging them to search for her at Jake’s cabin — her temperamental boyfriend’s place. Jake disappeared soon after, leaving behind a mystery that still haunts them today.

Other stories reveal roommates with bizarre and disturbing habits. One student lived with someone who barely showered and left the entire room reeking, while another dealt with a person who stuffed hair into the sink, constantly clogging it. There were also tales of filthy kitchens, cockroach infestations, and a roommate who would sit in the dark, muttering to himself about an “invisible roommate,” leaving everyone terrified.

Some experiences were downright dangerous. A woman’s brother lost his pet snake repeatedly in her apartment. Another person came home to a chilling moment when their roommate, who struggled with schizophrenia, mistook them for an intruder and told them to run for their life. Though it was a misunderstanding, it was terrifying enough for them to move out immediately.

These stories show that sharing a home can reveal unsettling truths about the people we think we know. From mystery disappearances to disturbing behaviors, living with others can sometimes be more like a horror movie than a sitcom — a reminder that not all roommates are what they seem.
