Let's see here: Fear of getting cut, fear of getting burnt and fear of mannequins.
Okay, the first two have a story. When I was young, I accidentally broke a window and a large shard of glass flew into my forearm and naturally it quite bled a lot and I have a scar on that spot still. The scar seems to have shrunk after these very numerous years, though. Note that I am not scared of getting cut when preparing food or doing other stuff with sharp objects, but rather the concept of intentionally cutting myself. For example like when hunters cut their hand open to get blood scent to a trap.
Then we have the burning incident, or incidents rather. When I was about 2 or 3 years old, I was in my grandfather's kitchen in Finland. There they had a space between a cupboard and a refrigerator which I decided to stand between. While I was there, I accidentally yanked a cable leading to a coffee percolator which then got stuck between my back and the cupboard. A boiling hot percolator and coffee pouring down, you get the point. Effectively half of my back had second or third degree burns. Then years after that, when I was a few years older, I was going to the sauna in which my grandfather was holding a big scoop of water, you know those with several liters of capacity, and it was filled with boiling water. He accidentally got bumped into by either me or my brother, and he ended up dropping the entire contents of the scoop onto my back which again suffered quite bad burns. Since then, I have been afraid of getting burned.
And then I'm scared of mannequins because they are just freaking scary. Every time, in the back of my head, I think about the plastic human-like figures starting to move, grabbing me when I get close or some shit. They land right in the uncanny valley for me, and actually got my heart beating pretty good during the mannequin sequence in Condemned 2.
TL;DR - I am scared of getting cut and burned because of previous injuries, I am scared of mannequins because they're scary.
