Most unusual fears you have and why

The song "what a wonderful world" terrifies me for some reason. Like I just get incredibly uncomfortable and anxious listening to it and idk why.
Also I'm constantly afraid of biting my tongue off and then like drowning in my own blood.
I can't listen to calming music or those like "ambiance to help you sleep" stuff cuz I get really paranoid about jump scares being included in them

Those are the current ones, but I've had a lot of weird fears throughout my life. I used to be scared my heart was a caterpillar that was one day going to turn into a butterfly and kill me. For a while I was also afraid of cannibals hiding under cars that would grab my ankles and drag me under to eat me. I was afraid of invisible walls appearing in front of me. A lot of weird specific stuff like that idk.
