Well, since I was a little child, I always suffered from a really specific phobia which is called vermiphobia (also known as helminthophobia or scoleciphobia), the fear of worms. It includes both, parasitic and non-parasitic worms. So, it was for me no difference if it is a earthworm, a nematoda (like a round worm), a tapeworm or a leech. When I saw a worm, I flipped out and run away. Rainy days were the horror in my childhood since the ways are full of earthworms (besides the fact that other chidlren made fun of it and came to me while holding earthworms in their hands tp scare me). Well, except for the parasitic ones, it is a totally irrational fear and with the time, I overcome my fear of worms. I mean, I am an educated gardener and the best friend of every gardener is the earthworm. I even watch videos or pictures were worms are in it (like a documantation of parasitic worms from a german speaking youtube biologist), but in my youth, I even could not that. I honestly don't know how this fear began, but it was really heavy. I was also for some kind afraid of snails, but not that hard as for worms.
As a child, I also had another strange fear. I was afraid of the sound of sirens (like when the fire fighters are alarmed). I also don#t know how this arose, but I also overcome with it ... I mean, I was part of the youth firefighters later.
