Chillingham castle

(You go to Chillingham castle for your 16th birthday, sleeping in the guards tower apartment for a night and going on a ghost tour, nothing too scary had happened so far, so imagine your surprise when in Edward I's old room, you feel a presence next to the window. You try to ignore it, but then later when everyone else has left the room you take a photo of the old fashioned window. There's a pale figure in the reflection of the window on the photo, staring at you.)
