Oh... okay, well mine is related to my clautrophobia on international flights. Before getting on a plane I have to call at least three people to let them that I'm flying and there's a chance that some terrorist may smuggle an explosive device onto the plane, setting it off, and whoever isn't instantly incinerated will likely be sent hurtling towards earth in a fiery ball of death. Either that or a giant hole blasted into the side of the plane... instantly sucking out half the passengers, still belted into their seats, plunging to earth at rushing speeds, until finally splatting into the ground and splintering into a hundred pieces of bodyparts. If I don't acknowledge that it could happen, I'm convinced I will go down in a fiery ball of death.
