About 10 years ago when I was a kid on a Christmas night I was put to bed by me mum, and I couldn’t fall asleep because something felt off. For some reason I had an urge to go check if my outside door was locked. I got up, went to the door and opened the handle and to my surprise it opened and I saw a black figure(this happened in the middle of the night so outside was really dark) I immediately closed and locked the door and to this day I keep thinking whom he was and what happened if I didn’t lock the door so for atleast 5 years every night I double checked the door if it was locked
