its all in your head. Just relax. Sleep with the tv on or a radio on. Are you a believer in the lord?? well if you are/or not... pray for the lord to remove the whispering and creaking and whatever else you here... when my husband works out of town I freak myself out sometimes... by thinking i hear something but its not really there. (-: I would pray myself to sleep and I also sleep with the television on. :-) goodluck.
Don't sweat it. It's just the ghosts, the evil spirits or the demons circling over your bed. Seriously dude, what are you afraid of? Try working out or exercising to the point of fatigue, take a warm shower, eat a meal and relax. I think sleep will find you.
