I heard a story where a roommate was really noisy at night. He would play loud music and talk on the phone late into the night. This made it impossible for his roommate to study or sleep well. The situation got so bad that the affected roommate had to move out in the middle of the semester.
One horror story is about a strange noise. A student in the dorm would always hear scratching at night. It seemed to come from the wall. He thought it might be rats at first, but the noise was too rhythmic. Eventually, he found out that the previous tenant had carved some words into the wall and the old paint was slowly peeling off, which made that spooky sound.
A very common horror story is about the roommate with bad hygiene. They don't wash themselves or their clothes regularly. It makes the dorm smell awful. Then there's the roommate who is always borrowing things and never returns them. It can be small things like a pen or bigger things like a laptop charger. And some roommates are just too clingy. They follow you everywhere and don't give you any personal space.
One of my friends had a roommate who never cleaned. The room smelled so bad all the time. There were dirty dishes everywhere and piles of unwashed clothes. My friend tried to talk to him, but he just didn't care.
There was also a dorm where a girl saw a figure in the hallway late at night. It was a dark, shadowy form that seemed to be floating. She was terrified and ran back to her room. After some investigation, it was discovered that the old building had some light reflections from outside that created the illusion of a figure due to the angle of the hallway and the window.
One of my dorm roommate horror stories was that my roommate never cleaned. The room smelled so bad. There were dirty clothes everywhere, and he even left food to rot on his desk. It was disgusting and made the whole living space unbearable.
One of my friends had a roommate who would stay up all night talking to herself. It was really creepy. She would mumble things that didn't make sense and sometimes even laugh out loud in the middle of the night. My friend was so scared that she ended up moving out after a few weeks.
One common element is the lack of respect for personal space. Roommates might use your things without permission, like borrowing your laptop or going through your drawers. Another is the issue of cleanliness. Some roommates are slobs and leave a mess everywhere. And then there's the noise problem. Roommates who play loud music or have friends over late at night can be a real horror.
My roommate used to steal my things. Small things at first, like pens and notebooks. But then it got worse. He took my expensive headphones. When I confronted him, he denied it until I found them in his stuff.
One horror roommate story is about a girl whose roommate would steal her things. The girl would find her clothes missing or her makeup used up. And the roommate always denied it. It was really creepy as she could never trust her roommate and always had to be on guard.
One horror story is about a student who constantly heard strange scratching noises coming from inside the walls at night. It was so loud that it kept her awake. She reported it to the dorm management but they found nothing. Later, she found out that a raccoon had made a nest in the attic above her room.
