Is it true that if you have a birthmark in your eye you can see ghost's?

i have had super natural expenses, like i feel that somethings in the room or i see something that no one Else can see.. then my teacher was on the computer researching information about the eye and she said in one web site it said that if you have a mark of some kind in or on your eye so can see supernatural things... i have a gray mark in my eye and so does one of my friends and we both have experience scary things that other ppl can not see.. is the gray spot the cause of this
