I was a real scaredy cat as a kid, so for me Terminator and Jurassic Park were the ones I remember giving me nightmares that other people would know. Outside of that weirdly the movie “the edge” with its bear terrified me, I always imagined a bear could just rip through the wall of our home and grab me. Another weird one was The 13th Warrior, there was a particular scene in.a bloody cabin that really upset me, but I dont think the movie was really scary, I was probably just way too young to watch it
