The Sound Is… Bizarre
In most cases, if you notice a disturbance in your house, you can fairly quickly determine what it is and where it is coming from. In the background, one might occasionally hear the sound of water trickling or a grating.
On the other hand, these homeowners couldn’t figure out where the peculiar sounds came from. They were unsuccessful in their attempts to determine the source of the noise, no matter how hard they tried. From how it sounded, it seemed as if the noise had spread to all areas of the house. From this point forward, things are only going to get worse.
