Pretty sure she meant actual events in real life.
I went snorkeling with my dad off the Napili Bay in Maui several years ago. We were going to an especially rocky area of the bay where large sea turtles tend to congregate and eat the seaweed growing on the sharp volcanic boulders. The current was extremely strong in some parts, and there was no real way to tell before it was too late. I got caught in a current, and if I had not swam out to the side of it, I would have been forced against a rock completely covered in sea urchins. In my haste to get out of the current, I kick a rock, slicing the top middle joint of one of my toes. The cut was really clean, thanks to the rock's volcanic formation. However, you'd be just as surprised as I was to see how much blood could come out of a toe when I got inside our apartment. A considerable amount. It ended up leaving a distinct scar where the cut was, and it will probably never fade by the looks of it. I have no complaints, since it could have ended a lot worse.
