Spend time with an apocalypticist, one who has a strong religious belief in the apocalypse, and you may develop hexakosioihexekontahexaphobia, the fear of the number 666. I have a touch of coulrophobia, the irrational fear of clowns. No, wait, the fear of clowns, as I see it, is absolutely sane and rational. Worst of all however, might be phobophobia, the fear of phobias, or the fear of fear. With this one, you are really up the creek. Especially if you have aquaphobia, the fear of water.
