Cobra Kai

In the winter when it's below zero, I hear loud thuds in the attic.  It's caused by thermal expansion.

Mine is Odell. The elderly dude that lived in my house before me, passed away.

I don't actually believe that, but there's definitely odd things that happen, doors opening, etc-we just say it's Odell, and let it go, if he's a spirit, he's not terribly mean or anything, so it could be worse.

The source of the disturbance turned out to be a ceiling tile that fell out. I found it on the floor behind the tv when I was picking up around the house. I'm glad I found out what happened, it was driving me nuts.
