Mine is being buried alive - I can't even stand to watch it happen to someone in a movie. I saw one once where this girl was kidnapped and the guy put her in a coffin with about 72 hours worth of oxygen and a light that came on and off -
Same for me!! even about the airplane! I went to Paris once and made myself go up to the top of the Eiffle Tower cuz I figured I might never be there again, but I was scare to death! Even when other people are close to the edge of something high it freaks me out.
Biggest fear is getting in an accident of some sort but not dying, just paralyzed and in a chair like Steven Hawking. If this actually happened I would need to take a trip to the Grand Canyon for some site seeing afterwards. Then do the scooter chair scoot to the bottom for a dirt nap.
