There are many wild animals I would probably never want to run into, that I would be petrified of. First would be a snake that suddenly fell into my personal space. Oh God. I would have a heart attack for sure!
Then if a bear came to my tent and started shredding it up...luckily I don't really have many bears to worry about here in south Florida. I always worry about them when we are in the mountains though.
And, last but not least, I fear alligators and crocs in the wild. This is a reality here...and we just had a bit of a scare at a nature preserve a few weeks ago. We were on a boardwalk out over the water, and the water came right up on the shore to the path out. A rather large gator swam over to where we were, and we were fairly concerned about walking back to the car. These creatures may or may not try to attack, but it still scares you. There had been a couple with a baby in a stroller who had just left, and we were so relieved they had gotten out of there...I could see something happening where no one realized the danger. The area was wet, a lot of shrubbery around the waters edge...I was watching for gators and listening too as we walked in...definately spooky. I will not go back there...no way!
