I think most of us have strange, unconscious fears. These are things we would never argue or claim out loud, which we’re barely even conscious of, but which guide our actions more than we realize.
For instance, many people have the idea that if they say “I have never been stung by a wasp,” it will guarantee that they will be stung before long. Now, no one would actually claim in so many words that what they say influences the insect kingdom, but it’s a kind of half-conscious notion arising from a combination of hearsay (everyone loves an irony story), superstition, and unexamined experience (that is, most everyone has had the experience of a thing happening for the first time shortly after commenting that it has never happened).
For me, I realized that when I’m praying for something, I feel like I have to be very specific and explain exactly what I mean for fear that, if I’m not, I’ll get something that is technically what I wanted, but the worst possible example of it. Basically imagining God and the Saints in the role of those evil genies who always grant wishes as maliciously as possible. E.g. if I ask St. Joseph to find me a job, I have the idea he might answer with, “son, there is a crab boat with your name on it!”
Obviously, this isn’t the case; God loves us, and the Saints presumably have left any malicious humor behind. The nice thing about these fears is that once you recognize them, they fade pretty easily as they’re so patently absurd.
