When did you stop being afraid of the dark?

Kind of a weird one to ask at this hour, but I was driving back from a late call-out and the thought just sat with me. I still remember being nine and convinced the shadow in my room was a person. Now I'm the person standing in other people's dark hallways at 2am, and honestly the fear just... moved somewhere else. Were you ever afraid? When did it stop, or did it just change shape?
