Spiders would be near the top of the list. When I was 18 I saw my first [and last] horror movie - can’t even remember now what it was called. For years afterwards I had screaming nightmares occasionally - I dreamt that a giant hairy spider was lowering itself onto my face while I slept. I still can’t sleep in a room where there’s an insect buzzing around - just in case it would land on my face.
