On my old place I once woke up in the middle of the night because there was noise outside and a blue light was blinking. When I looked out of the window there was a fire brigade on the street underneath my balcony.
And because I was still drowsy I thought the fire was in my building and I started packing a bag because I thought there would be an evacuation. But than I realized it was in another building and the fire wasn't that big. So I went back sleeping
