“Being in a state referred to staring fixedly and without expression at something for extensive periods of time. It can happen when you haven't had enough sleep, or too much sleep, or if you've overeaten, or are distracted, or merely daydreaming. It is not daydreaming, however, because it involves gazing at something. Staring at it. Usually something straight ahead—a shelf on a bookcase, or the centerpiece on the dining room table, or your daughter or child. But in a stare, you are really not looking at this thing you are seeming to stare at, you are not even really noticing it—however, neither are you thinking of something else. You in truth are not doing anything, mentally, but you are doing it fixedly, with what appears to be intent concentration. It is as if one's concentration becomes stuck the way an auto's wheels can be stuck in the snow, turning rapidly without going forward, although it looks like intent concentration.”
