Um...shot in the dark here, Hydra, but it sounds like it could be that what you're talking about is more to do with the mind than the eye: that what is in our thoughts tends to "appear" in a host of things. Occurrences, conversations, etc. during the day sometimes influence what we dream at night; if you're at that "mad" stage of love, then the whole world is rosy, and every other girl is at least semi-consciously compared to your sweetie, etc.; my son drove for a private ambulance company this summer--although I had seen their ambulances around town before, this summer for the first time I saw them wherever I went!
