When I was in college I rented a room in a house with three other people, one of whom made a habit of coming home plastered in the middle of the night. Several times I would wake up to hear the mistakeable sounds of drunk cooking. I would roll out of bed to go stop my roomate from burning the damn house down, only to arrive to a dark kitchen. Nothing out of place. Roomate still gone.

My other roomies had similar experiences when they were home, coming to make sure drunk cooking was supervised, only to find no one there. The guy who owned the house also reported hearing someone in big heavy work boots coming up and down the stairs, but nothing was ever there.

It wasn't a town house, and there was yard between the houses so I couldn't chalk it up to hearing the neighbors. Plus both nieghbors had young kids and worked alot, so I couldn't picture them drunk cooking so loud at 2am we heard it in our house. So I dunno. Super weird.
