The fuck are you doing on Spam if there's an intruder in your house?
I've got no one else to talk to and Yahoo answers sure ain't going to help

It might be the house contracting or expanding due to changes in temperature and other variables. If you aren't sure, grab something that can be used as a weapon and a bright flashlight and check your windows and doors. If you know for sure, call the cops.
I will call them In the morning if I still have the spooks
