It was the middle of the night, you were sleeping in your bedroom after a tiring day.

At some point you heard a strange knocking downstairs, which was getting louder and louder. Suddenly you heard the sound of breaking glass.... someone had broken into your house.

After a few minutes you heard footsteps, it seems that the person downstairs is searching through your belongings. You concluded that he is now in the living room.... but they could come upstairs to your room at any time...
