It's simple. I just want to know what frightens you. Be it a fear you've had but never faced, or a situation that was all to real.
My fear. Drowning.
I was between eighty and a hundred feet down. I'd dove past the reef, and decided to swim with the sharks that skirted this underwater sheer drop. Normally not a big deal, Smallish sharks that'll mostly leave you alone. Anyway, I had about another hour of air according to my tank. Less than a minute later, I was tapped. Went to inhale and it locked up. That far under water with a faulty tank surrounded by sharks. I was terrified. I think that was the first moment I really felt fear. I was without air for what I'd assume was ninety seconds before I could signal to my dad. He brought is backup line and I lived, but I haven't gone under since then. I did manage to have a bit of a panic attack snorkeling though.
What are your fears?
