Being terrified of the air ducts behind my walls making noise

And it was making a lot of noise for me.

Not a lot of things tend to scare me. I guess you could say that I am mostly just scared of the unknown. I am scared of not knowing what is going to happen. I am scared of having no idea of things that are out there. One night I was watching a movie and I suddenly heard a terrible sound. I heard the sound everywhere in my house. However I could never find where the noise was coming from. I could also not figure out what the noise was. So I kept following it all over the house. And eventually it lead me to the wall. I checked everywhere except I noticed that the noise was louder when I put my ear against the wall. It was really starting to freak me out. I thought that there was something behind my wall. However when I thought about it it was probably my air ducts. I noticed that my air ducts were behind my wall. I know that it could be an air duct collapse that could make a lot of noise. It was probably rubbing up against the wall or up against the other air ducts. And it was making a lot of noise for me. However I am happy that I figured it out. Because it was really starting to freak me out. Once I knew where the noise was coming from I was able to call the HVAC company and tell them that I thought it was my air duct behind the wall. I still hope this noise goes away very soon.
