Just state your worst fear... if you can. MUHUHAHAHAHAHAHAHAHAHA!!!!
Okay... now that that is over with. Mine is kinda odd. Have you ever woken up and been completely unable to move? Not even an inch? You try to move something anything, but in vain? No matter how much you try to move you just lie there, completely still, then all of a sudden you jerk up with the full ablity to move? Thats my greatest fear, its like torture to me, and it happens fairly often. I said it was odd.
