My three main phobias are of spiders, injections and zombies. Spiders because of their weird, alien appearance along with their fangs, which can be poisonous. Injections because of the pain? mainly with the horrid feeling of metal penetrating your skin, and the fact they have the potentiality in taking away a life than saving one. Zombies because the idea of being eaten alive and the fact you would turn into one of them if bitten.
Entomophobia, specifically mosquitos (en.wikipedia.org/wiki/Mosquito ). I'm allergic to their "bite" and they look terrifying D: It's getting better but there was a time I couldn't even grab something to kill them, I just petrified
I'm afraid of dogs (thisis my "inner panic", when a dog approaches and I have little or no place to move and avoid contact, I kinda freeze) and butterflies/moths (this shit gaves me full panic, I cant even touch a painting of those...).
That habit people have when they crack their bones (Be it knuckles or sometimes the neck) It just creeps me out and it all started from that Korean Bok Choy Ghost comic. The comic had animation and sound which added the scaryness. I cried for awhile and had to drown out the image with funny videos.
