Every night when I finally drag myself away from MN and crawl into bed, after ive turned thelights off and am just about to go to sleep I hear strange scratchy and scrunchy noises. So I turn the light on to have a look and theres nothing.... so I turn it back off and silently wait and it comes back... use the light on the phone to san the room and still see nothing... then I get freaked out, grab my pillows and run off to DS2s room.... help!! What is it or I am going slowly crazy....
