House Noises?

I don't know what it is about tonight. I'm wrapped up, in my cosy, extra quilted, king size bed. I have my little lamp on the bedside table, providing a warm comforting glow illuminating my stuffed bear collection.
Looking around, everything looks the same it just doesn't feel the same.
I turn off my lamp, deciding just to stop being paranoid. We all have these feelings from time to time, right?
Laying there, I hear far more clearly, just little things, house noises I believe they are called.
Static fills my ears, my body is preparing itself, but for what?
