Funny Scary Clips

It is very difficult to describe, but it can be funny or scary. It is a music / sound you hear in movies when something scary or gross and spotted someone watching with big eyes and disgust ... It's a sound I hear in my head when I look in my cats litter box.
I wanted to find an audio or music files with him.
If anyone knows what the heck I'm talking about, Please Help!

It's like ... Dun Dun Dun Dun dun dun dun dun!
As you are looking in the horror of your living room all tore your dog. or something.
