I'm not sure what this phobia is called but I'm really afraid of being near magnified objects and really high buildings. For example, during the Olympics how the 5 colorful joined olympic circles on the bottom of the pool look bigger than they really are when water is added in or even worse, if I were to go to a football game and a huge crowd of people are spelling something out with cards and the letters look like they are in a 2000 font. That is SO scary to me.
