No Single Solution
Even among an online community of people who set out to solve these kinds of problems, a majority of responders were stumped by what this family was experiencing. It was also hard for the family to explain the noises they were hearing in writing.
Proactive as ever, the family decided to sit and wait for the noise. Armed with pens and scrap pieces of paper, they were all going to listen and start describing what they heard, in order to help the forum members think about possible solutions.
Wretched and Loud
The next time it happened, the noise seemed to have amplified. It reminded them of something a large animal would make. The sound reverberated right through the house. This frightened everyone in the house.
Was it possible that the sound was coming from something otherworldly? All that mattered was that the family needed to figure it out quickly, as it was becoming somewhat unbearable to listen to the sound time and time again.
