Why are creaking noises scary? Like In Ju-On the grudge?

If you watch this video (http://youtube.com/watch?v=e8R1dODSbzU), you will hear at some point in the middle that there is a noise that sounds a bit like a creaking door. This noise frightens me. Why? The noise somehow makes me think of big scary insects.

I understand why the hiss sounds is scary, as it plays on our evolutionary fears of big cats, but what would make the door sound scary?

And it’s not because it reminds me of haunted houses – I never heard of those when I was growing up.

And it’s not the rattlesnake sound, as rattlesnakes are very limited geographically. But the rattlesnake does indeed incoorporate a similar sound into its defense mechanism.

Any ideas?
