First and foremost, polar bears. No clue why. Terrified. There was a taxidermy polar bear in attack position in Bob Wards that I saw out of the corner of my eye and freaked out. I burst into tears and had to sit on the curb while my friends got shit.
I'm also afraid of the feeling when I'm surfing, fall and get slammed on the reef or sand. I mean, I know I'm not drowning but holy shit. The pain of a reef cut, the wind knocked out of me and the fact that I'm being thrown around underwater is fucking horrible.
For some reason, I can convince myself that there is someone under my bed/car that is going to slash my Achilles tendons so every now and then I have to literally run and jump in/on. I guess that's pretty common though; half of my sorority agrees.
I think it's crazy how easily it is to convince yourself you're in danger. Like guys in windows and mountain lions stalking you and stuff. It's so easy.
