My boyfriend works night shift, and I was asleep alone in the house. I get woken up in the middle of the night by my puppy whining in the living room, and I assume it's because he wants outside. I'm just about to open the back door, when I hear this weird scratching/clicking sound at the front door, like someone was sticking something in the lock. I go to check, and I can see the silhouette of somebody standing there through the window in the door. I then notice there is a second figure in the living room window, although it's too dark to make out any features. I know they can see me because I didn't have any blinds at this point, and they just stood there. I totally freaked and called the cops, then my dad. I huddled in the kitchen out of sight of any windows and waited for someone to come. My parents live across town and showed up before the cops. They were gone at this point, but the neighbours across the street were up and saw the car. I ended up staying at my parents place that night, and when I came home the next morning, I noticed the basement window was partially kicked in. I got a security system installed the next day. I still have no idea who it was.
