I had a dream last night I was trying to stupify two Death Eaters by pointing my finger at them and yelling "Stupify!" as they ran evasively around the room. One of them finally stopped running around long enough to tell me I would probably have better luck if I got the pH of the curse just right. I nodded knowingly and then went at it again. After I woke up I realized what I really needed was a wand. Silly me!!
