Get a candlestick and prepare to ambush the intruder.
From Create Your Own Story
You reach out and grab the candlestick as you get out of your bed, clad only in your nightcap and bed robes. As the sound of the stair stomping intensifies, you hide beside the door, candlestick raised. Stifling a yawn, you watch as the black garbed intruder walks into your room, perhaps expecting you to still be asleep even after all his noise.
Take down the intruder with the candlestick. It should be easy.
