I was staying at my grandparents' place and their spare bedroom has a large window leading to a huge (like the size of a room) abandoned aviary.
Well, I woke up in the night, looked up, and saw my reflection in the window. Being half asleep, I thought it was another person and shouted, "Ah! There's a girl in the aviary!".
