What are the scariest elements in duplex horror stories?

One duplex horror story could be about strange noises coming from the other side of the duplex at night. Every night, the tenant would hear scratching and faint whispers. They thought it was just their imagination at first, but then things started to move around in their own side of the duplex when they were out. It was as if some unseen force from the other unit was invading their space.
