Tap at the window

A tap, tap, tap at the window, I hear it once again
Who is out there, what do they want? It's driving me insane
The roof is creaking as the wind howls into a raging gale
I look at her, she turns around and her face has gone quite pale
The dog cowers in his bed, the cat has now disappeared
There's a mighty crash now things are much worse than we feared
