Any psychologists in the house? Need help determining if I'm insane!

[Lovecrafty]

Seriously. Since I was a child I have this compulsion that has both annoyed and amused me. Maybe you can help. Sometimes when I'm driving down the road I will unconsciously hold my breath while looking out the window at the passing landscape looking for some random object. The object might be anything with the color red in it, or the letter F, or the number 4. I will try to hold my breath until spotting said object out the window. I tell myself that if I can hold my breath until spotting the object then something good will happen in the future, like finding money or getting laid! So the pressure is on! I MUST not take a breath until I find that object! I'll frantically look at license plates, billboards, mailboxes, you name it! Sometimes the pain will become unbearable and I HAVE to breath, at which point I tell myself I "lost" and something bad will happen now!!!

So am I insane? What does this mean? I've always done this as far as I can remember. Am I the only one? Does anyone else have this strange compulsion? If so, I sure would like to know!
