When I was a kid (I’m guessing 5), there was a house nearby where my grandma lived which had a statue of a small dog outside their house. The eyes on this statue were made of glass, and looked incredibly real. I remember standing there staring at the thing, extremely tempted to try and touch the eyes just so I could convince myself that the thing wasn’t alive 🤣. I probably stood there for about 5 min before I finally got the courage to touch it and realized it was just glass.
I was convinced that thing was going to bite me when I touched it.
Really, a better question would be what didn’t frighten me as a kid, but my most disruptive fear was of construction equipment (excavators, backhoes, etc). When I was in kindergarten, I refused to get out of the car to go to school for nearly a week because there was construction being finished on the school grounds.
