The apartment was strange, to say the least. It had no windows, and no doors. Yet somehow, the residents who lived there were never seen outside of it. People whispered about what might be going on inside, about the strange noises they heard coming from the apartment in the middle of the night.
One day, a brave group of friends decided to investigate. They snuck into the building and made their way up to the floor where the apartment was located. When they arrived, they found that the door wasn't really a door at all, but a solid wall. They knocked, but there was no answer. They tried to break in, but the wall was too solid.
Eventually, they gave up and left the building, but they couldn't shake the feeling that something was off about that apartment. It continued to haunt them for weeks, until they finally decided to move away from the building and never look back.
