Frogs and Lizards.
Was super scared of frogs when I was real young, like I would have reoccurring nightmares about Frogs killing everyone on Earth and I would be the last person alive. It didn't prevent me from doing anything, but if I was playing outside and there was a frog in the area, I would go to the opposite side of wherever I was at.
Still hate frogs, but not scare of them all anymore. Still find them creepy as **** though.
