In concept, going on a deep dive in the ocean is a supremely peaceful experience. You have finally escaped all the endless chatter and noise of human beings, and now you can swim through the watery gorgeous blue abyss.
While diving can be a rare and peaceful communion with nature, it can also serve up a soaking panic attack when you come across dangerous creatures and cadavers down below.
In a popular Reddit thread, deep divers and water lovers shared stories of getting scared to death by the deep sea, and as it turns out - sharks are big and mean business.
I don't know if this counts but I'm a water lover, so maybe so.
While water skiing in the lake one time (Louisiana) when I flew off I landed like pretty much on top of an alligator. I kinda felt my leg hit him and we were like eye to eye when I gasped for air. Then he went under. The moments after that were the most terrifying moments of my life because I was so certain I'd feel him bite my foot any second and drag me under. I started screaming and couldn't stop until the boat was back to me.
