Sounds From the Walls

So, I've rented this house for about six months now. I thought it would get better but I'm growing more concerned over the sounds I hear when I'm alone that others have heard, too. It's a house, not apartment so it isn't noises from neighbors.

It's just soft whispers like a conversation. Almost like listening to a news channel on low volume.

My cat stares at the empty shower fur on end all the time, just glaring up at the curtain whether open or pulled across.
